I couldn’t get the authentication thingy to work, so I just left moderation on. That way you won’t have to worry about comment spam and the like because it will simply never get published to the blog. This does mean that it might at times take a little while before your comment goes up, however.
Well the most recent decongestant has kicked in, so back to bed with me!
[Edited later to add: Got the authentication thingie to work, so all you need is a TypeKey ID to log in!]
