Thanks for the quick reply.
Actually this groupchat spamming wouldn't be a problem, because most of the people I know don't communicate over chat. They allways use Teamspeak and if someone doesn't like it while you are in a random group, there should be a button to turn the function off
Maybe there is a way to filter the dumping text, like ...
"if there is any number in the text, then dump to groupchat"
Such a solution would be best, I guess...
My only problem after all will be that I'm a total programming noob
