Actually not. The level editor should include all smb tiles to allow playing them with diferrent mapskins. They are fun.
No. No double post, or triple post, or quadruple post, etc. If you have anything to add, use the shiny edit button to edit your previous post, unless someone already posted. Even then, posts like that aren't really acceptable even if it isn't a double post. Since it doesn't really contribute to the topic, the post is pointless. Please keep this in mind so hopefully the mods don't ban you in the future.
