How to place a (+) sign next to every forum leaders name on the board?
 

I want all forum leaders (mods, admins etc) to have a unique sign next to their names in where ever the username is (thread information, whats goin on box etc) except postbit and user profile page
How can I do this?

An easy way to do this would be to utilize username markups. Go to your Usergroup Manager and edit whichever group you would like to add a symbol to.

Then in the two boxes for "Username HTML Markup" type this:

Box 1: <span>
Box 2: +</span>

(You can replace the + with anything you want)

See my attachment if you're not sure. This will make the symbol appear every time and anywhere the username is displayed. I'm not sure about excluding certain places but I'm pretty sure that will require some code edits or a mod perhaps.
