If you want to discuss features, tips, tricks or contribute to the
development of GIMP, then we have several useful mailing lists and IRC channels for you.
- GIMP User
- The original (mostly unix based) user list. For the everyday user.
Here you will find tips for doing cool effects, user questions, etc.
- GIMP Announce (not active anymore)
- Learn of the new releases of the source code (tarballs) without all of
the help and development. This is a very low-traffic list.
- GIMPwin-Users (not active anymore)
- Especially for users of the Windows version of GIMP.
- GIMP Developer
- The GIMP developer list. For plug-in developers and core program
developers; discussion about the source code.
- GEGL Developer
- The GEGL developer list. For developers interested in
contributing to GEGL, the new
architecture for image processing.
- GIMP Web
- The GIMP web list. For discussion about the contents and
structure of this web site.
- GIMP Docs
- The GIMP documentation list. For discussion about the
GIMP User Manual and all derivative works.
- GIMPI is a group dedicated to exchange of images created or
manipulated with GIMP.
When sending mails to the lists there are some recommendations you
should follow to make everyone's life easier:
The topic is GIMP. Stay on topic. If the discussion goes
off topic, use direct mail and not the mailing list. GIMP User
list topics are user problems, techniques, hardware advice
(tablets, scanners, monitors), request for comments about images
and usage in general. GIMP Devel list topics are coding, patches,
bugs and other GIMP's guts things.
Use the English language. English is the official
language of the lists. There is people from all around the globe
so we use it. If you have problems with English, a small note in
your message saying so is enough, and never apologise. Listing
which languages do you speak better will also help. Maybe someone
can help clarifying the obscure parts of your mail.
Check your facts. Before reporting problems, check
again. Make sure you are following the intructions correctly and
that your version is not old (or that the problem also appears in
modern versions). It is very helpful to get a friend to test
your problem with other computer, maybe you discover what is your
problem, or can provide info about what cases are free (for
example bugs that only happen in Alpha computers).
Be aware of your readers.
- Do not use HTML formatted email.
Some people will have problems reading HTML formatted email
and will ignore you even if they have alternative methods to
view it (like reading the HTML code or launching a
browser). Others will flame you (some maybe even have bot
for that). So to be sure everyone can read it, use plain
text mail, with monospace font.
- Avoid sending email attachments. If you must, send only
useful attachments critical to what you're discussing. If it is
more than a few KB (say more than 10), you should/must upload
somewhere and post the URL instead.
- Compress attachments. If you must send an
attachement, use (the best) compression you can find for
attachments or URLs. Remember that you can compress .xcf
files with gzip or bzip2 (.xcf.gz or .xcf.bz2,
respec.). Those compressors are free and gratis and
at least gzip should be handled by all GIMP versions known,
so no excuses. For images you can use PNG (ie. when showing
bad results and you need the image to be the one you are
seeing in your monitor) or JPEG (asking how to do something,
so if the image is a bit damaged due JPEG algorithm, it does
- Keep lines short. Cut text lines to 70 or so
chars, so it can be viewed anywhere. If you have a big
screen, good for you, others do not or just want to use the
big monitor to have more than one thing on screen at the
same time. Most mail apps should do it for you.
Use the 7-bit ASCII character set.
Do not expect people to see other character sets beyond 7 bit ASCII
and images supported by GIMP. You can hope they will, but do not
think they will. The same applies to you, if you see text with weird
characters, maybe your computer has no support for them. Or you do
not have the loader plug-in for GIMP, if the problem is an error
with an image. Be permisive about these problems and never force
them (aka do not send things you are sure most people will be unable
to see, and make sure your mailer sets the correct MIME type, not a
Quote prior messages only for context.
When replying to messages, quote the important phrases to give
context. Use something like ">", "> "
(yep, ">" and space), "]" or any other
character(s) that seem logical. As most repetitive things, your mail
app should do it for you. But do not include the full mail again,
select that part not useful and delete them (yeah, another thing
computers can do, delete full areas).
Try to be grammatical.
Do not write all in one big chunk, use blank lines to separate
things. Also use blank lines to separate your text from quoted
text. Try to read 100 lines of text in one paragraph, then the same
text with some blank lines, each 5-10 lines (20-10 paragraphs).
Some people just ignore the things that they can not read easily.
No auto replies ("I am on holidays"). They just waste space, and
people will think they got something when they are only talking to a
bot. Unsubscribe or set you subscription to no mail mode if you
Filter your email.
If you have few time, you can filter the messages. Message headers
can help a lot to make your life easier, most mail apps can filter
by headers, or use a helper app for that. The subjects have tags to
help you identify mail if you sort by hand all incoming mail in one
mailbox. You can delete the tag and use different mailbox too (use
other header as filter, like X-BeenThere). Another option is to
receive the mails in digest mode, all in one mail, so it saves space
and you can scan the on-going talks quickly.
Include relevant information.
When posting reports, paste all the interesting info. Use common
(hehehe) sense to decide what, you do not need to post the size of
the computer box, but be ready to provide more info in next mails. A
good start is a small description of the computer (CPU family and
OS) plus versions of related software (GIMP, libraries, compiler)
and the steps you followed to find the problem (write your "How
to crash GIMP in X steps with Y tool" tutorial). If you have
the solution, even better.
If you receive spam, do not reply to it. The list has filters, but
they are not perfect. The best way to handle garbage is to ignore
it. In general, you should delete spam, via list or direct, cos the
best solution is to desintegrate the spammers, and the second best
to ignore them (guess which one is legal).
No spam, or even a hint of spam allowed. No chain
letters, no virus alarms, only GIMP. Violating this is
equivalent to asking to be removed from the list.
Follow those before you.
If you have doubts about the rules, read the archives. Or subscribe
and just read it until you see how things are. We do not bite people
for just reading, but some can get very unfriendly with those that
ignore the basic rules. We do not ask for ultra complex things and
etiquette, but things that computers can do for you and a nice
behaviour on the rest. Most (if not all) of the rules have been in
use for very long on Internet (they are a tradition, but what is
more important is that they work).
Conclusion: the faster and easier people can see what is
going in the mails, the better for all. And the topic is GIMP.
