I am password protecting a directory on my site where members of our club will be able to login and access information. They will each have their own login and password. I've gone through the AOTA tutorial and everything is working (surprise!), but my questions are: What can the login and password consist of? Upper and lower case? Numbers? Are they case-sensitive? What is the minimum and maximum number of characters? Also, the tutorial tells us how to ADD new users and passwords and change passwords, but it doesn't tell us how to DELETE them. If a member leaves the club, I need to be able to delete his/her login and password.
