It always did have, but in the move over, it got lost.
The idea was if you wanted to talk to the zgemma people, you posted in the customer service area, it was for folk who had already bought a box from the site sponsor and got a code from them.
If you had a general enquiry, you posted in the section relevant to the particular box that you have and anyone could answer you.
I don't know if it is to stay this way, I will check it out with HT
