The the groups on transifex are pidgin for obvious reasons, and I had previously used guifications for my stuff that wasn't quite pidgin. I'm not opposed to putting gplugin under pidgin, but didn't want to do that directly. It shouldn't be a big deal to the move it, but I'll need to look at that if you don't have an issue with it being under pidgin.
Site question, do you want to be added to the transifex admins?
