If you have an active online community, can you sell coloured names in your forum, or little stars next to their name or something? Have a way for them to pay you money regularly in order to get a visual indicator that they're a big deal and clearly in to your thing more than the regular forum user. Maybe hint at their purchase giving their suggestions more weight in your eyes.
