After I add a user using
adduser, I can't see it via
System->Administration->Users and Groups unless I logout then login again. Is that normal?
Also, can I set a newly added user as a sudoer or do I have to change that only after adding it? How can I do that via the shell?
Finally, can I delete the original user that was created upon initial installation of ubuntu, or is this user somehow 'special'?
