Strange... the only thing I changed was to add an Issues tab[1]. I'm not sure why it worked before (I never tried to download the repo, only clone it), or why it broke. I agree that downloading a zipped file can be easier than cloning a repo (not by much, though). In that case, I may need to start a new GitHub repo, where the master branch is Arc/Nu (or whatever I want to call it). That would also be the time to do the rename.
