If you'd like to submit a map, please read the instructions over here: http://forums.manacube.com/threads/must-read-map-submission-information-format.649/ Include all the things listed there. Make sure to add where you build the parkour (creative/map maker world). If you built it in the map maker world, do /plot info to find the plot ID and write it down.
Feel free to PM me if you have any questions, thanks and good luck!
