Give it another try, I re-assigned to letting everybody comment so maybe it just needed that. If it doesn't let you join the community, maybe that's why? I've not idea why it's doing this to you :(

Sorry, it's put that everybody can comment even at that level. Can you comment at all? or is it not letting you? :O

Try it now. And please do let me know if there's any issues still :D

Thank you for letting us know. I will go turn that on right now!
