Pierre has put a call out for PHP developers who would like to participate in a TestFest event to be held in Munich (and southern Germany).
Johannes and I are trying to organize one or more TestFest days. No PHP internal knowledge is required (like C knowledges), all you need is willing to help to improve PHP and a good mood.
If you'd like to participate, contact either Pierre (pierre at php dot net) or Johannes (johannes on php dot net) and they'll get in touch. If you're wondering what the TestFest is all about, checj out this page off the main PHP.net site for more information.
