The player is a n actual player on my server with his clan. I have a look on him on a regular basis. Can't tell any strange things, yet. But will have a look at the bans.txt to be sure next week.
Btw: Your scripts are really nice! I am starting to script my own stuff since a few weeks. But even for me as an long year developer it feels really disturbing sometimes. Arma is a strange thing :) would you give me a hint for a good blog or some nice docs?
