I had to do a reinstall of WordPress a while ago due to an attack, and have just been getting my old settings back. One of those is that I don’t do ‘active moderation’ – holding your comment in a queue until I get a chance to look at it. That setting had defaulted to ‘on’, so that a few of your posts had to wait. I’ve now turned it off so you should be able to comment immediately. I have enough filtering in place to catch most of the spam, and would rather let some stand until I can deal with it manually than put barriers in the way of the discussion here.
