Oh, I don't mind moderation. I even used to be a moderator for a newsgroup back in the day.
It's just that the popup (at least on my Chrome) was only visible for a split-second when I did Quick Reply, so I didn't get a chance to read it. This happened again with my last message. Only if I post from the Reply to Thread window it stays visible, oddly enough.
Back to the topic at hand. Your suggestion about the preview window might just be the solution I needed! Many thanks, I'll check it out.
