What exactly do you mean by end user manual?Things like "How to open a ticket" and "How to view existing tickets" or do you mean "end user" with an agent, so things like "How to transfer tickets to another department"?Just asking out of curiosity. I guess the only available documentation as of now is available at the wiki, over at the github wiki pages and on @[deleted] personal webpage tmib.net, but the info there is definitely not related to end user as far as I know - I think it's for admins (and agents) of osTicket.But you may want to take a look yourself ;)http://tmib.net/http://osticket.com/wikihttp://github.com/osTicket/osTicket-1.8/wiki
