Camdug is a Cambridge Based community developer group who's primary goal is to connect great developers and great people (sometimes both ;-D )! Sometimes we organise some tech events, but mostly chilling out relaxed sessions where folk can meet and get to make new friends and meet with old ones.
Please also checkout some of the other techie meetup groups in Cambridge; I won't list them here, because each week there's a new group. Glad you've picked Cambridge as the place to hang out for a bit, and we look forward to meeting you some time,
the dev guys in Cambridge.
p.s. if you're looking to start your own meetup group in Cambridge, we'll help you get the message out.
