I absolutely endorse CB's thoughts, as I have expressed elsewhere. If you have the commitment to run a Club at all, then the extra effort in maintaining a data base, however simple is well worth it.
When we established SCOFF (Google for more)way back when, one of the first ideas was a common entrance fee for member Clubs. But individual clubs maintained their own membership lists. Individuals joined the club of their choice thus maintaining the "my Club" feeling. My Club at the time, The Cutty Wren, Hythe, certainly held beach parties and even brought Boys & Girls marquees to Sidmouth about 1970. Now that was a CLUB. I seem to remember that for quite a while we didn't even reveal the forthcoming guest; our members turned up because it was folk club night.
