How do I upload/update my map?
To upload your beatmap, go in the editor and hit File > Upload Beatmap. This will make your beatmap available for others to download on the website and create a dedicated thread for discussion. Updating a map is the same process for a map that has already been uploaded.
Each user has a limited number of maps they can simultaneously upload. Leaving a map inactive for a month (by not updating it or not posting in its thread) will send it to the Beatmap Graveyard. To update a graveyarded beatmap, you need to revive it first.
