I was invited to join the XML London Programme Committee, probably to shut me up after I spent some of XML Prague talking Charles Foster into making the conference happen again this year. Geert Bormans, Tom Hillman and Andrew Sales have also joined, and Charles remains Chair.
XML London is happening on June 10-11 at University College London. The submission deadline is on March 21 and all you need to produce now is an extended abstract that outlines your full paper, and presentation.
