A few notes for those that haven't been following this for a while:
The Childminding Forum (www.childmindinghelp.co.uk/forum/) was set up by childminders for childminders but was bought a few months ago by the company that owns childcare.co.uk. This company is controlled by a serial internet entrepreneur who formed and later sold datingagency.com.
NCMA Local is part of NCMA and is (as I understand it) only open to members of that organisation, including childminders who have not yet been registered. NCMA has accepted nannies as members for some years, and is now preparing to include nursery workers and other pre-school carers and is changing its name to PACEY (Professional Association for Childcare and Early Years). The constitution of NCMA does not give its members any say in what it does. As a charity the NCMA is bound to follow its Charitable Objects, which are basically to promote high standards of childcare (not to represent childminders).
The SCMA Member Zone I believe has a forum open only to members of that association (membership is open to childminders in Scotland).
I do not believe that the NICMA has a forum.
UKChildminding.info is a closed Facebook group and publicly accessible (but restricted membership) forum. I cannot see any information as to who owns these (well Facebook own the Facebook group of course, that's how they work), or what criteria or checks there are for membership.
UKCMA is a Limited Company which invites subscriptions for membership. The company is constituted as a profit-making business which does not give its members any say in what it does. It does not have an online forum.
What childminders haven't got at the moment is any organisation which represents their interests alone, or provides an open forum which is not controlled for commercial gain.
