New member (since late Monday evening) here. Posted late Monday evening. It was moderated. Appeared the next morning, with replies. Here's where it gets odd. I replied to the replies and my reply was posted immediately. Cool! Then somebody else followed-up, I posted a reply and that one was moderated. It eventually appeared. Meanwhile I posted comments to two other threads, sometime yesterday (Tuesday), the moderation pop-up appeared and they've yet to appear.
Not a complaint, mind you. It just seemed a bit odd that my second post flowed right through and subsequent posts went into moderation, is all.
