what helix said, but if you choose not to use it, do not accept a single add on skype from any one claiming to be middle man, with out a post on your thread stating their skype name. then right click their username on skype and hit profile. check the real skype name to make sure it matches 100% the one the middleman uses. People change out letters or numbers or add periods, etc, to scam by impersonation. Major reason why we do not support middleman services currently.
