Just do it, and if they don't like it, and delete it, then we will know. A lot of TER rules only get found out like that anyway. Many rules are not clear, until someone breaks them.
However, looking at the OP in this thread, it does not mention location. Here is the quote:
"- No links to websites are allowed
- Text (one line only) is allowed but cannot be an ad type text, such as (not an all inclusive list) website, email, phone number or statement such as 'Call Me' or 'Come See Me'"
It doesn't say anything aobut location (but it does have the disclaimer that their list is not all inclusive). Anyway I think with "our" little board covering so much area (basically the whole world-except for the few areas that have their own regional boards) that location should be allowed, and as long as the ladies keep the post from sounding like an ad, it should be fine.
