I've sent out a dozen Friend Referrals and not gotten credit for the two that I know are now mebers of the site.

Do the members have to be here for a certain period of time or attain a certain number of points before they show up as a refferal?

No. It all depends on how they register. If you just sent em an email an maybe they went to www.pwned.com an registered....no points for you! fail!
