Forum:Customisation questions

Hey, been searching for ages through old supports, and still can't quite find what I need, so....
 * 1) How can I change the right side bar's look, not what it says or anything, just like the colour, so it contrasts more from the rest of the wiki's background colour, like this wiki, with the white background, and darker shadow?
 * 2) How do you change the chat moderator icon?
 * 3) Is it possible to make a different chat icon for various roles, admin, bcrat etc?
 * 4) Is it possible to make the chat background different from the wiki background colour?
 * 5) How do you change how and what shows up in the user profile page for admin/bcrat/etc?
