This thread prompted me to click on the link suggested by Grant. I found the instructions perfectly clear and admirably comprehensive: if I want to contact a community, I click next to their name, fill in my contact information and query, then click the green "contact a community" button....and wait for a response.
Dave, I have to say that I find your questions less clear, and perhaps that's part of the problem. I don't really know what you mean by "our" web page: who's "us?" Your community? Do you have one? Does it have a web page? If so, is it linked in the list of communities? I get the feeling you may be less than clear about the exact nature of what is here being called a "community," but I'm not sure about that either.
Hope my post comes across in the constructive spirit in which it is intended. I've found this site and its users almost uniformly supportive and friendly, once they understand what's asked.
