Right. So how big is a Jam?

A jam will need to be at least one team. We think that means a minimum size of about five people, but you might prove us wrong.

The more teams, the more fun. About fifteen or twenty people seems to be a nice size for a small Jam.

There is no upper limit to the size of a Jam. Similar events have been successful with 250 people at one location - it depends on the site, and the local organisation.
