Every time you create a new post, or edit an existing post, you have an option to mark the post as "sticky" which will ignore the date and time it was created and pin the post to the top of your page:
In order to post content from your blog posts automatically on your site, you can use one of our two Blog Widgets. On the page where you want the content to appear, add or edit a section and click on "widget." You can then choose either "Blog Feed" or "Sliding Blog Posts," allowing you to choose which blog you want and the number posts to display.
Finally, once you have a blog page in your site, you have the option to have the body of an email post automatically as a new blog post, using either the Rich Text or Mail Builder formats.
To get started, create a new email, and in Step 3, select the blog you want to post to from the drop down menu. The default is that the email will NOT create a new post, so you will need to make a selection each time.
