The Call for Papers for this year's FrOSCon has officially been announced:

We decided in cooperation with the FrOSCon team to hold a subconference this year. This means we will have our own track with talks and maybe workshops. We want to encourage you to propose a talk for this event.

The subconference will be in St. Augustin, near Bonn on August 23rd and 24th. You can check out complete details on when and where to submit your talk idea on the official Call for Papers page on the FrOSCon site. Topics suggested include innovative PHP products, testing in development and integrating PHP with other technology.

Sebastian Bergmann has posted about this year's FrOSCon 2008 and the Call for Papers they've issued:

Focus of the conference is a comprehensive range of talks about current topics in Free Software and Open Source. Furthermore, space will be provided for developers of free software and open source projects to organize their own developer meetings or even their own program.

This year will be the third annual FrOSCon and will be held near Bonn, Germany. Besides the main conference, there will also be a sub-conference that has a Call for Papers of its own.
