Eventum Issue / Bug Tracking System: I don’t know how long this has been out there, but the MySQL team wants to give you their trouble ticket tracking app, which I imagine has to be pretty good.
Eventum is a user-friendly and flexible issue tracking system that can be used by a support department to track incoming technical support requests, or by a software development team to quickly organize tasks and bugs. Eventum is used by the MySQL AB Technical Support team, and has allowed us to dramatically improve our response times.
The screenshots look good.
At work we use a product called Gemini from CounterSoft that does a pretty good job.
+1 for Gemini. That's what we use on my side project.
