I posted a question about forking git repos and having Kenai host the clones (similar to how Github and Gitorious work). http://kenai.com/projects/help/forums/general/topics/892-How-do-I-clone-or-fork-git-repositories-?

I wanted to make a formal feature request for this, since this feature isn't currently supported.

The basic idea is that you can visit a project that you have read-only access to. If you have some changes you'd like to make, you tell Kenai to fork the project. At this point a new repo is created that you have write access to. You clone the project, work on it locally, commit/push the changes up to your repo. When you're good and ready, you inform the project owner that you'd like to make a merge request through Kenai. When the owner wants he can pull down your repo and merge against his code.

I'm loving the site by the way. The best thing Kenai has going for it is the all-in-one forge solution with the ability to swap out which pieces you want (like Bugzilla vs. JIRA). Keep it up!
