Sorry, but I'm a REAL newbie when it comes to the internet. Anyway, how do I put my compositons up for people to see? Is it some HTML thing or what?

have you tried clicking managing attachment? It lets you upload the music file on your computer.

Can it be any file? Like Adobe or Finale?

We can open .midi, .mp3, and .mus files. Try attaching one of those. :yes:
