Post closed on me

I just tried to ask for help here. Owing no doubt to the ambiguity of whether to interpret code as example to be read for support or as, well, html to be interpreted in WordPress, my post reads wrong now. I went back and tried to reply to myself while supplying the code without angle brackets, in hope that’d show. But this time it wouldn’t let me do so because it marked my whole thread as closed! Which no doubt means no one else can reply to help me either. This is sinister, not to mention leaving me helpless.
