By design, WordPress blogs are inherently public. However, procomblogs.ca has additional privacy controls for you to limit how accessible your blog is to others.
To change these from your blog dashboard, click Settings > Reading.
Next, you must select a privacy option for your blog site. Note: if your class is using an aggregator blog, you must use the default (public) or “Discourage search engines from indexing this site” options. If you are not contributing to an aggregator blog, you may select from any of the other options.
