Ok added some more icons today and this thread explains how to set them up. I may add more overtime if we feel they are needed.
Icons update every hr so if after 2-3hrs yours isn't showing ask me and I'll look into it.
In order to show on the map you need to place a sign as such, the  are key to the map generator, if they arent added the icon wont show:-
[Choice from below]
Your text as will appear on map
The options avaliable are:-
[home] = Towns/Cities on the map
[nether] = Nether Gate
[station] = Train Station
[subway] = Pure Underground Stations (ie people may need to search rather than look for a building above ground.)PLEASE PLEASE
don't abuse this feature, if it becomes abused then I'll simply remove it. The idea is to label points of importance to aid all of us on the server so lets be adults about where we place them etc and how we word them to appear on the map.
For Nethergates it would be most helpful if people placed the sign ON the gate itself so that the icon shows EXACTLY on the map where it is
