I will answer these to the best of my ability. Hopefully one of the ZC members will confirm my answers or correct me if need be
Hi, was confused about whether or not I was a member through registration.
We do not currently maintain a public membership register, and registering on the forum does not directly imply membership in the Society.
Also, does anyone know the mailing address for the society?
We do not publicise a mailing address. I can't think of any good need for one. If you believe you require a mailing address for something, it would be best if you first clarified.
