hmm, that might be useful for staff that have only a couple, but some (like most of our admin) have like 5 or so different titles lol. That might seem excessive but it works for us.
For example, a staff member might have :
Administrator,
Support Staff (meaning part of their job is to support people),
Small Group Mod,
Small Group Co-ordindator,
Prayer Team
all associated with their account - and all are needed so our members easily know who to go to for what.
