How to?!

If your custom story is done, and up and running, go post it in the Showcase section in the forums for all of us to see. You can put some screenshots with it too to catch our attention.

Keep in mind though, that if this is just a simple "test map" you made to learn the editor, I'd advise that you don't upload it, as those are only for practice, and not something we need to see.
