I agree with the "Referral" Page.

I used to be a member of a website for couponing and there was a section that had paid membership and once you paid your dues you could add your link anywhere in your signature as well as in the special designated forum. They said they used those fees to help pay for the website.

I don't know if that is the type of program you would want here, but maybe once you reach Super member status (Or even a designated amount of posts)you can link a refferal or maybe a designated amounts of refferrals per quarter. I know that may be a pain to moderate though. But In this case I would make Super Members have the alotted referrals, because anyone could make up additional ids to get the additional referrals.

At the least, you could always mention that if someone wants to do a referral, they can always do a "paid clicks" submission. Maybe you could do a lower amount like $1 (I haven't paid a whole lot of attn to the denominations for that) that is only available to members or super members.

I know it might behard to get everyone agree and it seems no matter how hard you try, there is always someone who will be unhappy.

Maybe you can compile some of the most feasible ideas and ask the members to make a vote, through a poll.

Ok I hope I helped
