The English Chess Federation publishes its entire membership list for all to see (members and non-members alike can access this). This shows what type of membership people have paid for and when their membership expires. It does not of course give out private email addresses. I imagine it publishes the list so that tournament organisers can charge and subsequently pay over the correct levy for grading purposes.
Should we do something similar for the BGA?
