Focus for this bug day is Patch Love - touching bugs which have a patch
but not making progress to being resolved. With your help, some of these
bugs can be fixed in the next release, Thunderbird 3.
Patch Love is triage work - guiding the bug and patch - so you do not
need coding experience. http://wiki.mozilla.org/Thunderbird:QA_TestDay:2008-09-11 has tips,
starting points and links for more help. And help is available on IRC
should you need live advice while working on a bug.
