It IS kinda unfair to have in the same sections like "Featured skins" skins that are for WA2.x to appear upon skins for WA3/WA5.
Also I can tell you that this is one of the most reasons I'm for example kinda "away" so long time from here.
BUT since AOL is now about all Nullsoft team and AOL is a giant in this industry don't bother for this cause it don't costs it anything to have the website look like this, it makes money from this now and that is what matters for them.
Since all the skinners like me will move to another media player or create their own real FREE players with cross platform ability (Windows/Linus/MacOS etc.) AOL will wake up and reconsider to change some things in Winamp.com site.
This can happen tomorrow or in 5 years from now, I'm not sure about this but someday will happen
Until then we will see skinners in not that mood they were once upon the time.
For example go 1 year back from today and see how many skins was posted in this section........
