Okay, how about this concept for rewarding skinners:
WinCustomize starts running regular contests in which the top 10 skins in terms of downloads by users who are also subscribers get a percentage of the revenue we receive from new subscriptions.  It would be done for only certain sections so that we could highlight a given section for that period (and we could even have multiple sections featured in a given time).
So at the end of the 3 months, we would tally the # of downloads that were done by subsribers (best way to avoid download stuffing since it's hard to "stuff the ballot" that way).
So the top skin would get something like $200. Second place $150, third $100. Fourth $50. Fifth $25. Sixth through 10th $20. This would depend on the # of subscribers of course but it would be in this ballpark.
A given skin author could make the top 5 skins though and collect it all. So it would favor quality skins and quantity. 
So let's say we started the first one in January and focused it on WindowBlinds and Iconpackager. The following one might focus on DesktopX and CursorXP. And so forth.
What do you guys think?
