Faulty Reply Button, Instructables Glitch/bug, or Something Else?

I don't know if it's just me, or if other iblers are having this problem, but I cannot write a reply anymore. I don't know if I'm unable to write replies for a reason of if that's just a coincidence and this has happened to other people. Don't really know what's going on, but THIS, would happen right when I'm planning a post on my second gun,GREAT!
