It would be a monthly subscription to show your worlds into a public maps in wilds.
The subscription will include the private and extended private map for free and the ability to "publish" it so that there will be a chance for players to join into it when going into the wilds map.
Players who join into by chance can upvote or down-vote the map.
To get maps publish you have to get 10 players to upvote it in your private map and then you click the button a mod will review it to check for any thing that won't be allowed. (The person who publish the map will be informed if the map gets accept or denied)
