Is it possible to have a referral system for current members? Where a current member can make accounts for there referrals with no admin approval. Then for non referrals have one open thread to the public to introduce themselves with a link to there personal promotions or there work, and have a member voting system to vote in those prospective members? 5 votes total? Could make for a more interactive introduction for current members with the new prospects and generate a warm welcome or possibly a definate cold shoulder. Would that be more work for you or help you out in the long run if all that were possible? That way you can lock her down.
