There's a new post to the Zend Developer Zone about this month's Zend Framework Bug Hunt Days happening at the end of this week - the 17th and 18th of December.
This upcoming Thursday and Friday, 17-18 December 2009, Zend Framework will host its fourth monthly bug hunt. Each month, the community organizes to help reduce the number of open issues reported against the framework. Past events have netted over 100 issue closures over each two-day period; let's keep up the momentum!
To participate all you need to do is have signed a CLA so you can work with the code and then hang out Friday and Saturday in the #zftalk.dev channel on the Freenode IRC network and get to finding those bugs. You can find out more information on the event on the Zend Framework wiki.
