If you make a video on the map, that's fine, it advertises the map, but do credit me and link this in the description.

You can change the map and upload it, but it should be different. Don't just reupload the same map. Also, if you do upload a changed version, you still need to give me credit for the original map and link back to this page. Btw you can't just add a room or a block, that doesn't count, instead you should update a lot more, like add an area, video, or remake an area.
