I need a plugin that allows external clients to log in and only have to deal with one "page" in wordpress. It must be very easy for external clients to update the wordpress-page they have received, because it is no way to explain to everyone how they do it.
I also need a plugin that can make it possible for those same clients to enter their address where they are located. All addresses must reach either a map or organized in a list where you can select the nearest county.
Is there such plugins? Where? It does not matter if they cost money.
