Holding great events

Gathering ideas for Events and getting the members to interact. A good event is the honey that attracts people out of their homes.

How About 'Mensans doing Interesting Things'
One idea that has come from the USA conference is to find members who are doing interesting things and are willing to have other members tag along. We raised this at a meeting the other night and already there are people offering to take members to Medieval Pagents, sailing, rock climbing and other things. We are an interesting bunch. The big win is that these are easy to set up, don't exhaust the 'host' or the organisers, and giver members a chance to socialise with members and outsiders - good for their skills!

Setting up the Evening
I've noticed that if people arrive at an event with 'expectations' that they will have a good time, they usually do. How to get that idea across early?
