Markus Wolff has posted today about the next PHP unconference happening in Hamburg, Germany:
The remaining question was not if, but when should we do the next one? This question can now be answered: On the weekend of April 26th / 27th, the PHP Unconference 2008 will once again take place in our beautiful city.
They're going with the mix of predefined sessions and on-the-spot talks given by anyone that wants to get up to speak (proposed to the group attending and selected based on the popularity). It will be held there at the local University there in Hamburg again. You can keep up with the latest information on the unconfernece over on its (German only) blog.
