Topic: Change Style
Okay, now that you've read that, let me say this:
I want to allow a user to change their preferred style via a drop-down box. When a user selects the style from the drop-down box (which is in a PHP file called styler.php in the root directory which is included into the main.tpl file) and hits "Change" (or whatever the Submit button says), it would set a cookie containing the preferred style. The header.php file would load the preferred style from the cookie instead of the user profile. If the style doesn't exist, or if no style is set, it would set a cookie containing the default style (which is already set in the forum's config). I'm not too good at PHP (yet, anyways), so any suggestions would be nice.
Edit: (Edited for clarity.)
