I know it's away from this site, but in the interest of sharing ideas and information, I manage "Cricket Coaches Worldwide" which is a coaches group / forum on Linked In. We have over 2,500 coaches actively involved in discussions. With coaches ranging from new comers to cricket with basic questions and discussions, through to international coaches like John Buchanan and Darren Lehmann.
Its understandable if you don't want to offer people a portal outside of this site, however in the interest of sharing info I'm sure many people would find it useful.
