Wine Bug Day is a chance to help the Wine developers focus on Wine development by doing some of the QA work for them. We make sure bugs are still there in the latest Wine so they don't have to.
If you'd like to get involved and maybe even have a bit of fun triaging bugs with a group of people, check out the wiki page at http://wiki.winehq.org/BugDay
The wiki page has some suggestions for easy bugs to target, such as bugs in your favorite application and bugs with a free testable download.
Our goal for this Bug Day will be to continue on the success of the first: http://yokozar.org/blog/archives/107 -- last time we hit over 70 bugs, and this time I'm betting we can top 100.
I (and others) will be in the IRC channel during bug day fielding all your questions, so please feel free to join in and rock some bugs :)
Thanks, Scott Ritchie
