Can't find Plasma Filter
I just started the tutorials for Gimp, and this tutorial: https://www.gimp.org/tutorials/Floating_Logo/ called for using the Plasma filter, which wasn't there. So I found the Plugin Registry, https://docs.gimp.org/2.6/en/bibliography.html#bibliography-online-gimp-plugin-plasma2 but the Plasma2 link took me to a 404 error page. Is this plugin still available?
