Do you have a local U3A (University of the Third Age)? They probably have a web site and the person who does that is probably more than happy to tell you how they made it. I did one for our group using Front Page 2000, which was as easy as pie, but it now uses out of date code. You could use Front Page 2003 which is more up to date - look on ebay.
I am finding Expression Web, FP's replacement, a real headache, although it is a challenge!
Another idea is to see if your county has a website with links to various social activities. They may even have a template for you to use.
