That's because the forum is hosted by Nabble, and is not affected by being a follower of the blog. It seems that just creating a username at Nabble does not make you "registered" with them.
Click on your username towards the top of the embedded forum section of the page and you'll see a prompt that tells you of the benefits of registering, e.g. it allows you to get email notifications, and, as I have discovered, add an avatar to your account.
I'm also Osbert! I'm now registered, but I think I've found a major flaw in what otherwise looks like a good solution: One can't select to have all posts sent to you via email - ie to use this as an email list (I would expect to see this in one of the settings menu, but it's not). You can however choose to have the posts in a particular thread emailed.

No! I don't think that's it. I guessing slightly but believe that the subscription offered is for the level that you are currently at. i.e.
Go to the [Options] menu in a particular thread and you get offered a subscription for that thread.
Go to the [Options] menu in a particular folder (e.g. Members Gallery) and you get offered a subscription for all threads in that folder.
Go to the [Options] menu in root forum and you get offered a subscription for all threads in the entire forum.
