Q: How do I reset the password for a user account?

This is for per-group user accounts; reset a password by loading the accounts screen, locating the name of the user you'd like to reset the password for, and then put a semi-colon after their name followed by the new password. Don't touch the lines for any other users. So it should look like:

Bob

Joe

Billy;newpass

Sue

Jenny

If you add semi-colons to other users it will reset their passwords. Similarly, if you delete them from the list it will remove their user account. So be careful to just change the one that you want.
