For the database field labeled "Location", in the memberlist, how about splitting that into two fields. One would be "State", or "State/Province", etc., and the second would be "City".
This way, when doing a sort of member's locations, you could sort just on the state, and or the city.
Say I want to see who lives in Colorado, I would sort "State" in ascending order and scroll down to all entries with Colorado. Now, I have to scroll through the whole list because people enter the name of the city followed by the state. So maybe the very last entry might be "Zitherville Colorado" (Probably no such town).
Also, maybe we could encourage members to at least post what state they live in. Too many members don't post any location.
Just my 3 cents worth. Scubaduber (aka Paul and Jan)
