Just an update on my previous post. Public comments in OU blog are now working (I hope - I'm about to test it), so you can leave comments on this post even if you don't have an OU login.

If you have an OU blog like this one and you want to use the feature, see the previous post for information about how to turn it on for your own blog posts. You have to select it for each post, it won't happen by accident.
