It may be that it's just not something xen does out of the box, or that I dont know how to do it, but our vBulletin forum doesnt allow users to customise there avatar pictures, we do it in a "trophy" kind of way where as you get more known on the forum, or do certain things you get a different title, with this comes a different avatar picture.
Exactly the same principles as the "new member" and "well known member" titles, but instead done through user groups and custom avatar pictures.
My question is, can I do this in xen?
I have read up about custom user group styling, and I understand there is a "staff" class that can be tweaked, but is there any way I (for example) add to extra.css the user group I wish to change and then point it to the custom avatar picture on the server?
Can I allocate a set picture depending on what user group they are in?
