There's a 'contact us' link on the home page.
Thanks it was the HCV one.
I went for a visit and found it closed.
Heard the woman that runs it is a member here,Jenny? I have important phone numbers in my Pm box there and am anxious to retrieve them.
I never heard it mentioned around here. These people may point you in the right direction.

Sorry don't know what it is.
