The PHP-QA team would like to announce the TestFest for the month of May 2008. The TestFest is an event that aims at improving the code coverage of the test suite for the PHP language itself. As part of this event, local User Groups (UG) are invited to join the TestFest. These UGs can meet physically or come together virtually. The point however is that people network to learn together. Aside from being an opportunity for all of you to make friends with like minded people in your (virtual) community, it also will hopefully reduce the work load for the PHP.net mentors.

All it takes is someone to organize a UG to spearhead the event and to get others involved in writing phpt tests. The submissions will then be reviewed by members of php.net before getting included in the official test suite. Please visit the TestFest homepage to get additional details on the TestFest on how to get involved, either as a UG or by setting up the necessary infrastructure.

Once again we are glad to announce that we have been accepted to be a Google Summer of Code project. See our program for this year's GSoC.

We would like to take this opportunity to say thanks to Google Inc. for this privilege to participate once again, and would like to invite everyone to look at our list of ideas: http://wiki.php.net/gsoc/2008. Students are of course more than welcome to come up with their own ideas for their proposals and we will consider each and every application that we will receive.

So once again, thanks to everyone who is involved in this magnificent journey and we hope to see many of you great students and open source passionate join us in our most enjoyable Google Summer of Code projects.
