Responsible use of Invites! - 04/05/14
As usual, when invites come out people get up to shenanigans. Please be aware that invites are for people you know, not for someone your friend asks you to invite.
Be 100% certain that the person you are inviting is trustworthy, because your account is at risk if they turn out to be bad (as in a trader). So before you invite them, think would you lend them $20? If you would, go ahead, if you won't ... don't invite them!
