Customer Ticket Tracking

I have found one of the best open source ticket tracking systems so far to be OSTICKET. I have been using it since 1.6 (still use 1.6 daily to keep track of customer tickets), but it works great, it’s easy and open source. They offer a hosted solution as well. I’ve already customized my 1.6 version to be the way I want it so I’m still stuck on that version, but 1.8.1 looks great and seems to do a good job. Maybe one day I’ll move to the new version, but they got a bit advanced in their PHP and it’s more complicated for a basic user like me. I strongly suggest the use of OSTicket.
