The idea is simple. Create a group if one doesn't exist, and then put a trigger in it. The problem is that the permGroup() call doesn't create a group called "AlexK", just a trigger with an id, and then the permRegexTrigger call doesn't do anything because there is no "AlexK" group to put it in.
I tried to figure out what the solution is, since there seem to be a few mentions of it on the forums, but its still not working for me.
