As users of WordPress, we are extremely lucky to have access to a WordPress plugin to handle this function for us. WP-Sticky is a WordPress plugin that adds a few new options to your blog. Once you’ve uploaded and activated this plugin, you will have a ‘Post Sticky Status’ menu in your Write panel at your disposal. You can then use this menu to flag your posts as an announcement or sticky post.

For those wondering what exactly it means to mark something as a sticky or announcement, flagging a post as an announcement will cause the post to permanently be featured as the very top post on your blog, while flagging your post as a sticky will only keep it as the top post for the duration of that day. Starting the next day, it will move back to its published order.
