Sometimes it would be useful if the access level of a user are visible.

Maybe behind or below the username - for example in Bugnotes:

Mister X
(Reporter)

The other users could see how "reliable" the user is. Or which access level he has in a private project. Maybe a user is a developer but is downgraded to a reporter in a private project - so the others could see, that he is only a reporter in that project if he add a bug or bugnote.

This should be optional.
