Unable to comment on WP Polyglots / make.wp

In the meantime, a post (not a reply) I made on Polyglots was apparently accpted ( http://make.wordpress.org/polyglots/2014/02/05/theres-a-lot-of-ghost-untranslated-strings/ ) but if I try to reply to my own post, I get a message saying “error ocurred, comment not posted” or something like that (I couldn’t take a note, sorry).

If I try again I get “duplicate comment, you have already said that” even though the comment isn’t anywhere

Looks like is is solved. Is there a way to edit comments? The keyboard shortcuts shows “e” for editing, but pressing it has no effect, and I can’t see an edit link anywhere.
