There is a developer day on 22nd October in Reading at the MS campus. After the event there will be a Geek dinner in the evening since there are a load of developers together in the same location...
I know that at the last developer day I didn't have time to meet even half of the developers there and would have loved the opportunity to get together over dinner with some of them to find out more of what they do etc.
I have spoken with the organisers of the developer day and a geek dinner is on the cards after the event, subject to venue and people wanting to attend. To sign up go to the Developer Day Geek Dinner wiki and add yourself to the list.
We are looking for venues at the moment so if you know of anywhere that would make a really good venue add it to the list or vote for it on the wiki
