We have been hosted for free at WordPress, and we are very grateful for that. Over the next week or so we will be moving over to a hosted account. This is so that we can add new features to the blog, set up a mailing list, host more in depth articles and set up a discussion forum (or at least one that looks less than ten years old and allows for more than one thread).
These things will be rolled out slowly, but be prepared for an address change.
If you want to join our mailing list early, and get forum access, earlier access to articles as well as exclusive special offers then please email us.
