I have recently added the Blogger comment system. From now on I will use this and not the Haloscan commenting. I now automatically receive Blogger comments as emails so they are much easier to keep track of. However, the main reason I have changed commenting is because Haloscan wouldn’t let me comment as the IP is on the OPM blacklist.
Anyway, ignore the “old comment” links on the left of the page and use the comment function at the centre below each post.
