something similar that might be cool would be a location search option. So what you would do is type in your zip code and a certain mile radius, and any members who have their location listed, and are within that range would show up as a search result. That way, if people wanted to team up and work together, it would be easier to get people together and in touch.
personally, I live on cape cod, and other than asking my friends for help (none of which are 405th members), I feel stranded from all of the other 405th members.
