The PHP Unconference takes place on September 12, 2009 and September 13, 2009 at Geomatikum, Hamburg University, Germany.
A key factor to the success of an unconference is that the attendees get involved. The content of the sessions and the decision on which sessions are actually held, lie in the hands of the attendees.
As of yesterday, you can submit your interests and contributions. These submissions form the basis of the session voting process on Saturday and Sunday morning. A session can be a lecture, discussion or workshop with a maximum length of 45 minutes.

If you look carefully at the list of submissions, you may find one that deals with word processing document generation with PHP. :-)
