Exactly, the club can't afford to rely on one or even 2 people to keep the site together.
We're in a much better place now than we were with the old site. The old site was 100% custom. At least now if the worst came to the worst and this site could no longer run then the forum database can be installed in a bog standard version of vBulletin and it'll work away without loss of membership information or posts.
Maybe a new tact would be to have an individual or company install version 5 when it's released and have them find modern plugins that do the jobs of the current custom stuff. The challenge there will be finding applications that give us the control people want. When I wrote this site the specification was very exact, there were no plugins that came close to what we wanted and what we had been used to with the old site. I suspect these days there would not be as much concern with the exact specification. There are less active CM to please
