I support the possibility of choosing color shemes very much!
I tried to make my personal website with very proper css - so that I can easily change it's style or let the surfers choose. But soon I saw that this isn't that easy (just changing the css) as this standard ins't very well impemented in some browsers (they let it appear differntly)
I use FireFox and it would be
easy to change RHP's css and use my own - but it is not (for me).
So I just hope for this and other cool features to come on this wonderful website!
