Do not worry about your little experience in 日本語, we are all learning here, I am probably at the same level you are maybe a little higher, but thats about it.
Register an account on the blog, and I will add you in as an author.
Edit: P.S We will all be working together to create the blog entries, so we will be able to learn from each other, correct each other, you will be able to learn something new everyday.
