Account maintainance commands
Within commands below, Don't take square brackets, angle brackets and triple-dots literally:

< This > should be replaced with your own info - including the angle brackets
[This] is optional parts of the command - including the square brackets
... means "repeat ad libitum" - leave it out or add more stuff similar to that right before the dots

Normal users
Create new account

Pick a username:


Start with the initials of the user
Include also second letter of either first name or surname
If necessary, add third letter of first name or surname (or a trailing number)
The result should be practical (short and related to the name of the user) but must not be a nickname or initals: A username is comparable to the shape of a key - the user may get confused in every day use if it looks like a toy or jewelery!

localadduser <username> <fullname> <cellphone> [<otherphone>] <addresshint> [<addresshint>...]


Full name: Full name (Capital and small letters allowed, as is space and special characters, but no comma!)
Cellphone: Cellphone number including country code but without other spaces. Like this: +45 40843136
Addresshint: local part of email address, followed by @-sign, and optionally followed by mailgroup. Like these: jonas@ js@pool_of_maildomains

Extend password lifespan
