osTicket
So I’d been looking for a free or open source online helpdesk solution for a long time, since I started at Rainham Mark in fact and at last I’ve finally found a good one! I’ve tried a lot of packages, but osTicket is hands down the best free one I’ve come accross. Easy to setup (php/mysql), supports e-mail routing to tickets via POP3 and highly configurable. Now if you want to submit a bug, complaint, query or feature request for any VBE Software program, just e-mail helpdesk@vbe-software.com and the system will take it from there. Win. </plug>
