Kona - then show your evidence. Here's a clue: You saying " a lot of people use X" doesn't make it true.
If Rainlendar is popular, then show us the proof.
Ignoring the statistics I painstakenly provided does not help your case. The Alexa score on the Rainlendar home page is very high. The # of documented downloads of its skins is low.
DesktopX, btw, is the third most popular desktop enhancement on the Internet.

Last week DesktopX got nearly 11,000 downloads.
So unless you have actual facts to back up your assertions, you're just making noise. As I said I think Rainlendar is a very nice program. I can see why some people would use it. I personally use DesktopX and not jsut because I work at Stardock.
I think I've been around long enough to recognize the difference between a cult following and mainstream appeal. Rainlendar has a small, vocal following. But it'll need to get beyond that. WinCustomize doesn't exist to put small apps into the major leagues. It is for those major apps to get to the next level and in turn WinCustomize benefits from the large following. It is a two-way relationship.
The question you guys need to answer is this: What is the benefit to WinCustomize of adding a Rainlendar section? Will it bring more users to WC? That is the litmus test. But there is no indication that there is a significant (in terms of number, not # of posts Kona) following for Rainlendar. The # of downloads of its skins is quite low and the home page for the program is currently not very popular.
There are lots of people who swear by skinnable editors, skinnable clocks, skinnable CPU meters, and so forth. To them, their favorite skinnable app is very popular. But it's not clear whether such specialty apps have enough popularity to be side by side with heavy weights like WindowBlinds, Media Player, IconPackager, Winamp, Litestep, etc.
