customization: themes last across sessions
Your theme choice will now persist for 180 days. I'm now building the stylesheet for this site dynamically from a PHP script that places values based on reading the client cookie. I should probably sanity check the values before plonking them in to the stylesheet, but that's for later.
I think I'm ready to extend my theme settings. Probably I should allow theming of font characteristics, plus link color combinations that work better with the overall theme. Also that lets me emulate well-know site color combinations a little better (Asylum, Guru's Network). Hmmm, should I do colored scrollbars to coordinate?
Next I'll put in a custom theme wizard, and a user theme submission page. Maybe a theme randomizer?
