I see ur plugin WP-Members
But I have some idea I want applied.
I want special plugin for my site but I prefer develop ur plugin.
My idea is when any member want registration he chose his county then will show dropdown for region then he will select the region then well show the cities in this region .
this information will show in blog beside member information and control panel in member area .
thin I want search engine if any member want search how is in his area by cities or region or country in blog and control panel .
How much does this work cost almost ?
