Invite code - will pay for feature

[onlinepeeps]

Hello,

I'm interested in buying your software but there is a particular feature I feel is missing from your features list that I was wondering if you offered it, but was not listed.

The feature i want is: I want each member that joins, join only when they have a sorta 'invite code'. Every new member will have a set of 'invite codes' to which they can send to others.

Each new member's invite code must be verified before allowing to join the community. Also each person that joins the community must be traceable via the 'invite code' they used in the first place.

Please let me know if you have this built in your system or not.

Thanks.
