I could be wrong, but I think the problem is there are too many Brain Pawns. Brain Pawns do not help the site because they do not pay any money. A site costs money to run.

Some people have indicated that the brain pawns need to be given more features or more games or less restrictions in order to entice them to become paying members.

Of course, this is preposterous. If a brain Pawn is given MORE than the already NUMEROUS features he has, why would he pay for a membership at that point?

Generally, I have found that I (and others) pay for something when they have a lot to gain from doing so.

How can it be made so that Brain Pawns have more to gain by paying for a membership? By giving them LESS, not more. THe less they have, the more they have to gain by becoming a paying member.
