Social media publicity.
In order to get more people join us during the event, social media is going to play it's own part. We'll be using all necessary hashtags including open source hashtag too. Also, posting of the event every hour to make them keep seeing it and also keep retweeting it. Words of mouth, DM with our friend's who we think would be interested in it. If possible we can send mails to every member in Gnome Africa.
