Every Tuesday we have a gathering of indie game developers at the CB2 Bistro in Cambridge. This is primarily a social event, and anyone is welcome to come along regardless of experience. There's no pressure for you to do anything at the meet but it's probably a good idea to bring a laptop so you can work on your own stuff while you're there.
Starting at 2pm and running until the evening around 9-10pm. We're upstairs usually at the back somewhere and we're pretty conspicuous as a bunch of game developers.

Twitter: For event discussion we usually post on twitter with hashtag #cb2indies
We also have two specific themed meet ups each month:
Show and Jam - On the first Tuesday of each month we'll be meeting up in CB2 as usual but this day will host an optional themed game jam for you take part in if you wish. Also we ask people to give us a "show and tell" of whatever project they've been working on for the past month.
Pub Outing - On the last Tuesday of each month we'll be putting the laptops away for a more social and drinking orientated meet up. We'll start off in CB2 as per usual but once it gets to around 5pm we'll move on to a nearby pub for an evening of frivolity.
