I had about 5 test ones in, which were just found online. They weren't really intended for use, but I was playing around with them to see if any were tweakable into something that was, or just to get some more experience with skins in general.
They were, of course, merely called things like "Pale Test #1" or "Dark Test #2", thus indicating their temporary/soon-to-be-deleted nature. Apparently Stuart failed to realise this, and has gone through and given them all proper names. Because, you know, he's a twit.
heheheh- I can make that the default if enough people like it- OR send me links to places/ colour schemes you like and i will mimic them! theoretically I could make everyone their own theme! (killing time ftw)
I'm also using Pale Test 1. The only issues I've seen with the other skins are the text being too low-contrast to comfortably read, and colors being too bright/intense/saturated. (Just, something to keep in mind if you keep tinkering with colors.)
