We had to switch to the new Source Forge project software ('classic' projects are no longer supported).
Unfortunately non-admins can no longer access the bugtracker and such. That's a know issue at SF and they're working on it.
To all of you that compile their own:
The above change also changed the URL of our git repository. In order to attach your existing local repo to the new location, issue the following commands:
git config remote.origin.url git://git.code.sf.net/p/ufoai/code
git config remote.origin.pushurl ssh://<SF-username>@git.code.sf.net/p/ufoai/code
That's it.
