Re: netID lengths

["Semmens, Theresa" <theresa.semmens () NDSU EDU>]

We use firstname.lastname with a 20 character limit.  The owner can shorten or change their name, but must follow 
procedure. Last name can only be changed if has been legally changed and has been registered in the ERP.  Name can be 
shortened, but must use as much of the last name as possible.

We also use 8. The initial value is based upon last name + first initial
+ tie-breaker characters, but the algorithm in use comes up with some
odd choices. At any rate, the user can change their assigned username once. Usernames are not permitted to be reused.
