ive just checked some random styles

SWFans
Style 64: i dont really like the very big header, and the way that the same brown color comes back in each table cell... looks kinda boring
Style 34: suits better for a Star Wars forum, but again the returning color in each table cell
Style 21: quite identical to style 34, just other colors and another header
Style 50: this style is quite nice, one that i'd choose, nice colors, nice embedded header, only a board wrapper and the style would be complete
Style 11: dont like it very much, quite simplistic, and the header is average and the colors dont fit too well

Meras
besides the colors i find the skin pretty cool, i like the way you did a background at the login / logout field. just the returning simple patterns make me puke (dots in this case) change it with some 3d image or something, like www.nlhd.com has
