Bug / Issue Trackers

I've been working on getting my PMP (Project Manager Professional) certification. While doing so, I have been reviewing materal and came to a part about an Issue log. This got me thinking about finding a server / client component I could use. I discovered a version of RT3 which is a tracker tool I use at work, but also saw Trac which is another tool. I decided I will look at both and see how they compare. Trac at least seems to provide default capabilities in Eclipse with the Mylyn plugin, so this may be preferrible. I forgot that Bugzilla is also available as well. We'll see how it goes.
