Don't believe who tell you that database saving for color changer is hard. I did an awesome color changer compatible with all browsers + db + cookie at the same time (some extra stuffs for this, linked to my forum), i had some headaches
but it still makable with some skills. But i don't think i will share it because most of shit developpers i contacted didn't want to help. and Aoki as you know, don't help when you talk about something he did for the forum
I could integer it into a plugin with a settings page like here but i don't think it'll be a good idea, if anyone hack my ftp he will get everything easily
Did it using extra php pages, some extra stuff & template editing & intelligence.
Maybe in the end of the month a plugin will be for sale here.
If you want to do anything you want to your forum without helpers, just learn to code.
