You dont need to submit H2H maps. Just copy the res file in your ahiiterr folder and select it when you start to host the room. If you need help with mapmaking, got questions (the editor *can* be a handful at times) - do a search on the topic in
Terrain Editor Forum . Or post your questions there - thats what wetrat wanted to say with 'wrong forum'

.
If you want to make a MA map, they need to be minimum 256x256 miles, three even sides and a fully operational strat system. No custom tiles or objects. For further details/instructions on MA maps, mail Skuzzy.
