All this guide is based on my own experience (approximately 2 years) on the KDE bug tracker.
It may not work for you ;)
If you are not familiar with the Bugzilla (KDE bug tracker system) interface, you may find this guide useful: Quick Introduction to Bugzilla
Manpower is always needed in a bug tracker, but as any action taken on it may be potentially destructive to other people's work; or it may end up messing things up (and consuming the developers' or other triager's time) the tracker requires special permissions to perform changes in bug reports.
If you want to work in the bug tracker you need to prove that you know what you are doing.
Initially you will ask for support on #kde-bugs (on IRC) and add comments in the bug report (so other people will see and check them, perform the needed actions, and evaluate your work)
