Sourceforge is one of the few left that support Mercurial, which I use.
But feel free to use SourceForge - fine by me. I just wish SF would hide unused stuff from the project page. The new UI is a ton better, but as an example, this project still has 'wiki' and 'git' links, even though they're both empty.
That's exactly the good thing, you don't have all those trolls and forced social interaction with A-holes.
