Sibylle: I'm horribly biased because I organise PHPNW but I do think it's a great conference and very much aimed at the grass roots of the industry rather than a showcase of the top levels. This year's event is on 8th and 9th October, is the best value for money in Europe IMHO, and you can find out more about it here http://conference.phpnw.org.uk. Feel free to get in touch if you have any specific questions, otherwise I hope I'll see you there - be sure to come and say hello!
