At the beginning of the guild year (Sept.), we are all divided into "teams" that each plan a monthly program, provide refreshments, design a block of the month, etc. The teams are pretty much chosen at random so we get to know each other. At that first meeting, teams sit together and then communicate via email and short meetings when needed after guild meetings. The larger the group, the harder it is to meet people, and some people do tend to be cliqueish.
