So to do this for real I would think we need to do the following;
1. List existing events which we could be part of.
2. Decide which events to "hook up with" (as it were) so that all regions are represented
3. Finalize schedule and get members to sign up to display.
4. Get support and word of mouth network going through other sites
5. Get together and have too much fun.
