Hi all.

I have an idea for a web site that will require allowing the user to search for people in a list I have compiled.

I need to allow the search to be location-based, in that the user can specify "within 50 miles from my zip code", etc. I did some preliminary Googling on geo-based searches, but I can't find anything that helping me.

I'd appreciate it if someone could point me in the right direction in regards to how to set up a location-based search.

Thanks for your help!
