Rightio, that’s me added the Haloscan commenting and trackback system to the blog. It should be self-explanatory; unfortunately it does mean that while existing comments are still on the various blog entries, they won’t show up as “Comments [3]” or whatever. Sorry.
One of the main advantages of Haloscan is that you can leave your name without having to sign up for a Blogger account or similar, and you can include a link to your web site as well. Needless to say, blatant comment spam will be deleted…
