Is there a way to make sure an EdBlog post stays at the top of the home page?

By default, EdBlog lists the most recent posts to the blog on the home page. In the event you want a special post to remain at the top regardless of new content, you may do so by making the post sticky.

To make a post sticky, click edit on the post. From the Edit Post screen, click edit next to visibility under the Publish block located in the upper right of the Edit Post screen. From the options provided, check the box next to "stick this post to the front page".

Now your post will stick to the top of the home page. If you post multiple sticky posts, they will be ordered chronologically.
