They will struggle to sign up members without having some form of a proposal to put to people to debate. The general idea of fixing the fixture calendar is good, but also needs the how/why/what/where/when issues dealt with.
Personally I would like to see the day/weekend dedicated as La na gClubbana to be one where every county in Ireland was playing championship at all levels. No county training permitted for 7 days before hand, with five figure fines for teams not releasing players back to their clubs (money to go to the club as an incentive to blow the whistle), (Any mystery injuries suddenly appearing to IC players to automatically rule them out of their next county match.) Then we will see if club really comes first, or if that is just a hollow marketing slogan.
Also county championships to recommence within 10-14 days (to give club teams some notice) of a county ending its participation in the IC championship.
These are off the top of my head with no real thought as to the logistics. There are a truck load of suggestions that they could put forward,and IMO it would make the CPA a far more attractive and meaningful proposition if they did.
