Unable to reply to Code thread

Sorry if this is a silly question - but I submitted my code in the share your code section of the forum. But now I am unable to post any replies to comments other people have made.

I don’t see any “Post”, “Comment”, “Reply” button on the site. I am logged in. Do I need to update some settings to be able to do so? See screenshot.
