I'm trying to create a sub-account but I keep getting a message that the names I choose are invalid. I know that there are rules for passwords and for sub account names, and I am following those rules. I'm not talking about already used names, like "John" -- that gets me the error message that the name is already being used.
I know that the "-" or the "_" or the "." can be used.There is a minimum (6) and maximum (30) limit on the number of characters in the name. If I follow all of those rules, why would it be invalid if it is not already in use by another user?
