"Nobody's done it" -- probably because it is "too advanced" ;-) e.g. To run your your own database for ZipCode proximity will take about 12.5 + 7.5 MB (how do I know that?) of raw data to load to MySql ++ the PHP logic to scan that for "proximities".. "Popular"? maybe so.. might be better luck to post on Professional Services or hire a Developer for that.. I just can't see anyone doing all that much code work for the pure love of GPL'ed PlugIns ;-(

@Matt If you want to find users through zip code you could use the profile manager plugin, create a zip code field, and use profile manager's advance search.

For thE 'people near you' you could use the people from the neighborhood plugin and edit it to only displays the users with the same zip code. I've done that for a dating project.

@RJC:=
Not *same ZipCode ;)
I think he wants something like
"Members within ## Miles of you"
And that should then scan for Members' ZipCodes within the distance specified..
That's how real Dating sites work - without limiting to just a small area by your ZipCode ;-o
