To sign up to participate, all you need to do is to register your blog with this website. Most people will do this as part of Thing 2, but I hear there are some people eagerly asking to register already (great!)
If you already have a blog and would like to register now, please fill out the form below.
If you don't already have a blog, that's ok too - the very first thing we'll look at is how to set up your own blog, and we'll take it from there.
