Bunch of assholes, so get ready to retaliate and run like hell.
But really most people are cool, just like with any other online site / forum someone will want to scam you especially being new they think you can be taken advantage of so the best defense is to use middlemen or just trade with reputable members that you see other people have trusted and that you trust yourself after talking to them. Always request a PM to verify someone is who hey claim to be and check Skypes to weed out imposters. I am sure you know most of this coming from another forum but even if you know something it is best to review.
Otherwise, read up on the rules. Try to post shit in the right section and don't spam your ass off, unless in the spam forum then go crazy.
