Currently, each BandHelper account just has two passwords -- one shared by all administrators, and another shared by all users who are not administrators. The reason for this setup is to reduce the times that your bandmates can't log in because they've forgotten their passwords. They can just ask someone else in the band for a reminder.
However, this has been confusing for some people. Has this setup saved you any effort, or should I just change to a more typical setup where every user has his or her own password?
