VIP installment plan suggestion

Created by: odmonk

odmonkg suggests: "Possible VIP modificiations: I was thinking you might get more VIP buy-in with lower levels having some minor benefit, but when they accumulate the equivalent of a higher level (like 15 or 25) they get that level for a limited time. For example, have a 5$ or 10$ level, if they keep the 5$ for 3 months they get 1 week of the 15$ level; 2 months later they get 1 week of the 25$ level. For the 10$ folks, they would get the 15$ level for two weeks after 2 months, and the 25$ level for two weeks after 3 months. (These are just examples, you may want to other combinations. The basic idea is to reward people for continuous contribution, even it they can't justify the 15$ or 25$ levels all the time, while keeping the value for people who are at those levels continually.)"

You could think of this as the "installment" plan for VIP.
