On June 24, 2011, join in the regular community event and squash some bugs along with fellow developers.
You may fix bugs at any time, but joining in a Bug Day makes it funnier, exchanging ideas and review requests via IRC (<link irc: irc.freenode.net _blank typo3 bug day irc>irc://irc.freenode.net/#typo3-bugday). The atmosphere is generally quite stimulating.
The <link http: wiki.typo3.org getting_ready_for_a_bug_day _blank about bug hunting in the typo3>Getting ready for a Bug Day page contains all relevant information, in particular about the setup you need to be an efficient bug hunter (code, tools, etc.). So don't fear joining even if you have never fixed bugs before. It may be a bit scary at first but you will learn a lot.
See you all very soon.
