Maybe user titles could be given out -or- taken/changed as a reward/punishment for various things.
Like;
helping people out lots despite not being an Angel
keeping out of trouble/not causing problems/dramas
contributing to the overall 'story' of the servers in some fashion.
Of course the title wouldn't be special in most cases, it would be more like a 'generic' title, like 'Wannabe Angel' for a player who is always helping people out.
Specific 'special/unique' titles for members would be few and far between.
Mind you, we the players, would not know what was needed to get a title.
Can't see this happening though, it'd be one extra thing for the Mods/Admin to do.
