Hi Jon,

And last but not least, how can I delete a user, who is no longer needed?

OpenTRS is working with database id references. If you would delete a user (or queue, ...) from the database, your delete the reference info. Important infos like owner or queue. Set the data record to invalid and the record is still visible (e. g. for ticket history, ...) but not activ for the application. The above was just an excerpt from Martin's reply to http://lists.otrs.org/pipermail/otrs/2002-August/000171.html Kind Regards, Pol
