sr.ht supports Mercurial as well. And fits well with the old-school vibe.
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.
Isn't it easier to switch your version control than keep trying to run a project on SourceForge? I know I find it almost impossible to interact with a project hosted there.
