Some other information I have received suggests that this was indeed a “work in progress” which has now stalled.
Quite frankly I rather think that attempting to run a list of this nature on this website is rather pointless since as soon as it is published it goes out of date as individual club details, contacts etc. change and there is no mechanism in place for updating it. Simply relying on people to tell you is no use at all.
My inclination would be to replace it with links to the MPBA, MYA etc. who do keep updated lists which are likely to remain reasonably accurate. For those clubs who don’t belong to any organisation a simple query on the Forum is likely to bring forth a response.
