From MSUK

For the first time ever in the UK, Microsoft is hosting a unique event for Developers to learn, share and hear from other Developers - NO Microsoft speakers will present. Held on a Saturday, DeveloperDeveloperDeveloper is designed to be an informal day; the agenda will be determined by the developer community. You will have the opportunity to see new faces present in a relaxed atmosphere. Activities will include presentations on a wide range of topics (see suggestions below), a networking area and fun zone.
