Looks like we had someone who signed up and was asking around for anyone to share his key. I just want to stress again that you should never share your key. No matter how nice the other person seems to be or whatever sad story he has. Not even if you think you can trust the other person.
We cant keep these guys out of ITST as they are not recognisable from the start. So its your own responsibility to keep your key to yourself. If someone does approach you through the pm system please let me know as soon as possible. Its from now on an instant ban for anyone who tries to gain a key this way through ITST.
