I stumbled upon an interesting site today: ohloh.net (recently acquired by SourceForge). I haven’t had a chance to look through it much yet but I noticed that the GIMP developers were listed in it. Actually, it was Martin Nordholts blog that pointed me to it.
I’m preparing a new release of XNotesPlus, completely rewritten in Java and renamed XNotesNG, and have been considering pushing the project to SourceForge. I may want to also add it here, although sourceforge may do that for me now. Just one other avenue to expose the application beyond freshmeat.net.
