2 hints:
Passworded maps
I found a simple way to open/test passworded Elite maps:
Enter Elite station -> LOCAL PLAY -> CREATE -> LAUNCH -> select downloaded maps -> PLAY
It is much faster then opening each map separately in editor, because you can freely jump between maps:
ESC -> MANAGE SERVER -> GO TO MAP
Link to a map
If you want create a link to a map you can use BB code.
Just type this:
[map]Map ID[/map]
More info about BB codes is
HERE.
