Daniel Holbach has announced the next Ubuntu Bug Day. This is an event where users and developers gather on IRC and go through the bug tracking system. There they prioritize, assign, and confirm bugs reported by users; this process is called triaging.
If you ever planned to get involved anywhere in the Ubuntu world, bug triage is definitely a good place to start … Now is the best time to get into Ubuntu development as well.
You can get a head start by learning how to help with bugs and then heading over to #ubuntu-bugs on irc.freenode.net. How to report Bugs effectively is also a good place to start if you like to report bugs.
