I understand what you are saying happyman but it doesn't actually get around the problem of getting active members. If you have a club membership of lets say 45 members and 15 are active you can indeed remove the other 30 that might play just every so often, however you are still only left with 15 active members so IMO you are actually making the club worse as at least some of those 30 will occasionally play.
Now I understand removing if your membership is at capacity and you want to make room for new members then yes go for it and remove the infrequent players or indeed remove any players that NEVER play but at the end of the day the core membership will be the core membership regardless og club membership numbers.
Don't be to hasty in removing members as I have been tolerant and now those members that never used to play in cc comps have started playing a few and we are gradually progressing. Anybody starting a CC and expecting to get a large playing field in club tourneys forget it, it takes time to build up a CC and most clubs with membership entries of 30 or more in comps have been around for a very long time.
