I don't know xca and I hope that it is a good project. Seeing a sourceforge link after the flack from the last few months makes me somewhat skeptical of the content on the other end though.
Yes. And hopefully that would be an impetus to move were that to happen. Any repo at one location that was at SF the day prior, and I knew they moves, immediately looks better in my eyes, because they are no longer helping support that system.
