Well, I had understood being muzzled to mean being moderated, like Michael said. So that's why I was confused when there were no "Post Reply" or "Start Thread" buttons. I thought maybe I had to accept the Forum Rules in order to do that, so I did that, but I was still unable to post at all. Even when I clicked the "Reply with Quote" button, it simply gave me a message saying I didn't have permission to perform that function.
(I had to wait until the muzzle came off to post this thread)
But maybe it was just a glitch on my account. Anyways, I'm unmuzzled now and I intend to keep it that way, so I don't have any further questions. Thank you both for your help.
