Allow moderators to use HTML in usertitles
 

Is there any way to do this?

Or at least a way I can set markup that goes before and after their usertitles automatically when they change it via their usercp (so they can have whatever they want as their usertitle, but have it still retain the colour/size/etc)

bump!

No there is no markup for titles, only for usernames.

So no mods/hacks available that can supply this feature?

There's already a setting when you edit someone's profile to choose either "User set" or "admin set (using html)" .. If the functionality exists there for admins to set people's usertitles with HTML in them, it shouldn't be too hard to make it so mods can too, should it?
