About blogging

I have writing class, it needs post my blog. I use computer everyday to check my blog and Gmail. I confused about what should I post to my blog the first time? There are some labels. For example, essay, books and more. Particularly, I confused about free-writing, It is free-writing. So it is not difficult, because everything is OK to posts. I always think when I post about free-writing. In addition, I'm not good at using computer, so it was difficult for me to use the blog before. But now, I can post anything.
