ClueSwap is about giving and receiving Clue.
Think of one thing you would like to learn about. Think of one thing that you could teach someone else. Those two pieces of information are all you need to attend ClueSwap.
Rather like an Eighties Children's TV show we will be putting together what people want to learn about with people who can teach it (or at least explain it and share the war stories).
Think of it as Open Spaces Learning or a BarCamp based around skills.
To try and get organised it would be great if you would visit the wiki page below and post some ideas about the Clue you're interested in (OpenId login required).
