Hi Jane, you have no need to worry in the Blogs section. Debates aren't allowed here. There are a different set of guidelines for the "Life stories and blogs" forum, and if someone posts something to your blog that you don't want to remain there, this is the only forum where you can request someone else's posts be removed from your thread. This is from the User Guidelines:

The "Life Stories & Blogs" board exists for members to chronicle their journeys. It's a place for personal narratives about relationships. While discussion of what's posted is expected, those threads are not a place for open debate--they are personal chronicles. If you read something there that you just have to debate, start a discussion about that topic on the General board. If you try to argue on somebody's personal story thread, the post can be removed at the request of the member who started the thread.
So, rest easy, blog away, and... welcome!
