Advanced zip code search for Dolphin

- possible to make the mod so that admin can choose wich Country can be used for Joining from Admin Area (Checkboxes?) - Datas should be stored in dolphin DB - optimize the distance searches? In my Live site I have a modded version for this, but I don't know what the coder has done there!? Coder told me that the zipcode function (distance) is not right! - Will be good If search results will show the distance from own Users zip code - will be also good if it's possible to sort by distance - will be good if distance from own zip code is showing in profiles Country= Germany 20 km from 88339 or 20 km from Bad Waldsee Note, both types can have more than one entrys (one Zip code can have more then one City! One City can have more than one zip codes!) Therefor there must be a list with possible zip codes and/or cities to choose by user! - sorting by distance in search results - correcting search stings - change from square to radius search - own profile should not show in search results any other Idea for this? Should be easy to install / Files and Install description has to provide!!
