You know, each sf project can have a "homepage" link, and I once spent half an hour searching for where to change it. I kid you not.
I have searched for 10 minutes on how to reply to a bug report and attach a patch. I gave up in the end.
I'm still the owner of a dead project on sourceforge. I've tried several times to delete that project, but there was always something that prevented me from doing it (I don't recall, I think the project had a mailing list, and I didn't have permission to delete the mailing list, and I couldn't delete the project without first deleting the mailing list. Or something.).
sourceforge simply isn't usable. The makers know that, which is why they do a big redesign/relaunch every two years or so -- but each one makes it worse.
Even then, the downloading experience is warped straight from the 90s.
SourceForge allows to host phpBB, Wordpress, MediaWiki, my custom php code, with gigabytes of disk space.
It's not possible to install all this software on Github or Google Code project.
