I will be talking at the Google Technology User Group meeting on Monday 12th May, about Google App Engine. There is some room left, so if you are interested, please sign up and come and mingle - there is a lot more than just my talk to see at these meetings, and the community is great.
You can find the signup page at http://sv-gtug.org/event/2008-05-12.html. I hope to see you there.
Cheers
Dick
