Just my thinking, and there may be administrative reasons why not that I'm not aware of, but what I was thinking was this...Add a resources section with separate forums depending on where the geographic need sems to be. If only mods could view members location info, perhaps they would be more likely to give it in their profile. For example, right away there seems to be concentrations of members in Australia, UK/Europe, Canada, and US probably broken into Southeast, Northeast, Central and Western. I'm assuming the site will continue to grow and a structure such as this would make it such that someone looking for local resources could find them without wading through pages of irrelevant info.
Again, just my $.02.
