User can edit/delete their custom titles only if they are allowed to do so. Under Member Management -> Profiles you can set which groups have access to editing their own custom titles.
All users are set to be able to use and edit custom titles. However, they cannot
delete them once they're set -- even I can't, via my profile. I can't blank it out - it comes back...
Edit: - Okay, in order to remove a custom title, right now, I have to put a space in the box and then submit it. It then clears it. I can't just clear the box like would be expected.
