Yeah, I'd seen that post over on multiboxing.com, and gave it a try when I was doing the level granting. The grantor side worked great, but the AcceptLevelGrant side never worked for some reason. That said, accepting was just a single mouse click, so I'd hit the (broadcast) key to grant the level, then click the mouse to accept it. Went pretty fast. I tried it on two different accounts so I'm reasonably sure that it wasn't a typo that was the problem.
