You don’t need to be a member to come to our events. They’re free (usually) for anyone who wants to come along.
That said, membership is free and you get to vote on things if you come to our very exciting general meetings.
Currently we’re moving to an online membership list, so if you want to be a full member with voting rights and so on, sign up here, and make sure to tick the box on your profile page. (We may also require that you turn up to at least a couple of events now and then.) We do not publish our membership list anywhere.
