Sadly I think there are a few bugs in this system. I have a spare account that I have been using for Debug for a couple years now (originally global accounts were not able to access debug so I was given a special account with access ONLY to debug), and it was set to adminlevel1. So when I got on admin panel and set an IP, it didn't really stick. It just stayed there and looked like it was, but it let me get on Debug where I had no IP set, and if I was at a friend's house it always let me on, as in it never checked it. Now on my global (Projectshifter) account it has always worked and such. But I think the system isn't working the way it was planned. I had a guy come to me, he gave me his admin account and pass to try to set it myself, and I set it properly for him repeatedly in admin panel, but it didn't update it locally in his rights, which is the problem. Not sure if this is a Robert or Stefan thign, but willing to be Robert could fix it considering he's tapped into the DB through a firewire cable to his left arm
Anyway, so that seems to be what's going on and a few people claim to be able to work it, while some don't seem to be able to, such as myself.
