Right, Have spoke to Mike and this is what he has said regarding the guild-
"Hi Pete
Thanks for your email.
Generally what we are trying to do is ensure that those that are aiming to profit from other members are the ones that have to pay to advertise. I am keen to support trade associations where there is mutual support for the forum so, bearing in mind I've not really looked at the post in question, my initial thought is that I'm happy for it to be advertised without charge. However, we obviously reserve the right to review this as we develop the site and the way it is run.
Hope that helps
Regards
Mike"
So thats the ruling from Mike himself. I think he has been very fair and wish to thank him for his willingness to work towards a compromise regarding this issue.
