[otrs] ticket creation w/o registration

Hello all, I've just installed otrs and don't configure it fully. There is some missing in docs I think, because there is no any chapters about how to get starting or step by step configuration. It's really difficult.. While I'm trying to configure it I have a question. Is it possible to make that the customers don't have to register first for posting the tickets. Maybe it's possible to have a form where they just put their name, email and message and when submit it they receive password and I have a ticket in system. Would be it's possible to do as I want? Thanks. -- Best regards, Alexander
