To protect a map, you need to download a map protector. Just chuck your map in and your map will be un-openable, but still play-able. There is one type of map protector that crashes WE if you try to open it and there's another one that deletes all triggers and variables when you open it. I don't know where to get a map protector though. You can ask Bear, he posted in the MM contest, he knows how to protect his maps. To send something through PM, just drop something into Paste Bin, then send the link. Paste bin is located in the right corner, above icons.
