This always seems to happen when I leave it for a few months.... I can't access the CVS repository. I'm starting to wonder, though, if a different website like Google code might work better.
I created "invade-earth" as a Google Code project. Let me know what your Google account email is so I can add you as an admin.
Re: Sourceforge
I have heard other people complain about Sourceforge as well. It looks like Google Code offers SVN, CVS, and other things, so it might be an better choice. It could also give the project more visibility than Sourceforge... the interface is a lot nicer, so people probably browse through projects more often. Worth a look?
