If you have mapped a beatmap you can upload it as a "Work in progress" Map.
In the Beatmap Editor there's a Tab in the top left corner called "File". As soon as you click on it there should be the option to upload the map. Don't forget to upload your map as WIP. You can find your map on your profile page. Just copy the link of your map and post it here.
Only this way other people can help you.
