I'm kind of confused, I followed the instructions on the first page and all that. But I'm not sure whats going on with it, once I have it all on it constantly /who's people but no matter what I choose as settings it doesn't seem to ever have people to invite. Like when I look at the /who list I can see a bunch of people unguilded but the add on isn't recognizing them or something? I tried purging the list with the /sgi purge thing thinking that it might have just bugged, but even after reinstalling it it still doesn't seem to like me.
E: Lolz, was some kind of problem with my WoW cache from when I had used it earlier. Cleared the cache and all is good now.
