You seem to like replying a lot without ever using the edit button. I'm going to try to answer all of your questions:

• You could temporarily upload your levels to some website with free hosting, and there's always the download section at J2O.

• You don't need to know what a hotel is. In fact, you're a lot better off not knowing what it is.

• I might want to play with you on your server if you aren't hosting something incredibly boring or overhosted (like battle1, battle2, and battle3).

• Reptile probably just took a screenshot while in the game (with F12) then edited it down to size with some paint program or whatnot. It's simple enough.
