I am starting this blog as a class assignment and was told by my instructor to be careful that my blogs do not expire and get removed after 30 days. She stated this is common with wordpress. I have to have the blogs I post available for the duration of the course so if they do expire is there anyway that I can change the settings to keep them on longer?
No, they do not expired. I’ve been with WP.COM for more than six years and have never heard of a blog being removed for anything other than violation of Terms of Service, or when owners delete their blogs.
