If you want to have a post that always remains at the top you can create a sticky post. 

To create a sticky post click Edit beside Visibility and tick ‘stick this post to the front page‘. The post will remain at the top of the page.

This is useful if you want to provide some standard information, or if you have an important update about which you want to inform users. It can also help protect against the user’s first impression of your site being a specific topic set by the latest post.

You can allow comments on all posts, however for the purposes of getting feedback on this template, please comment only on this post. To do so please click on Leave a Reply  above.
