We'll aim to meet once a month and discuss implementing MongoDB - mainly from the developer's perspective. MongoDB is a NoSQL database - more info on MongoDB is available at http://www.mongodb.org/ We'll also be following the MongoDB online training run by 10gen.
Venue for meetups is yet to be decided, but it will be in Cambridge. We'll wait to see how much interest there is before booking the Corn Exchange! We're also on the look out for sponsors and/or hosts, so if anyone can help out there, please get in touch!
