We're a random group of people who share an interest in Linux, living somewhere in the vicinity of Bromsgrove or Redditch (Worcestershire, UK). As of 6th August 2009, we meet every other month on the first Thursday, with meetings alternating between Redditch and Bromsgrove.
Membership is free - all you need to do is either sign up to mailing list, and occassionally contribute (or start) a discussion - which may be anything to do with Linux and open source software (e.g. Help?! How do I get XXX to work).
Alternatively, just turn up to a meeting - we normally try and pick relatively quiet venues, and there will normally be a Linux magazine (or a crowd of people wearing geeky t-shirts).
