Ideas for posts: Let me know what you want!

I've had some comments on this blog leading me to believe that these posts are helping students. I'd like to know more about who you are and what class you are taking. Is it a high school level class or other?

Email me at julieawissd@yahoo or leave a comment here.

Also: Do you have specific topics you would like me to write about here? What are they?`
