Some social networking websites require you to provide a postcode on sign up. When searching other online members, you are able to see other members in order of distance from your postcode.

My Question: How exactly is this done? I am requiring the same sort of thing for my website :)

The place I would look it is the Google map API. You can use the geo encoder for things like that.
