Just a quick note from over on the main PHP site - the people behind the LinuxTag this year have put out their formal "Request for Papers" for this year's conference.

Submit your ideas and proposals here. This year's theme looks at discussions that promote new ideas, delivers a broad overview, introduces new users to linux, or discusses the legal, moral and other implications of linux and free software.

There are all sorts of topics that could be covered - and I think they'll look at just about anything that's sent in. Of course, you'd also need to be able to get over to Germany to present it - but that's besides the point....
