Define permissions for the System level blog. Users with access can modify all aspects of the System level blog: modifying Blog Management options, creating new posts, editing / deleting any existing post.
Number of posts to display in the Recent Posts section in the sidebar and the system homepage's Blog section. When choosing a number, keep in mind that the homepage will display the post title / link and teaser text.
Links to your social media accounts will display in a "Follow Us" section in the sidebar of your system blog.
Set the defaults for social media sharing. Each setting can be modified on each post, meaning you can choose not to share a post at all or choose to share a specific post via Twitter and not Facebook (or vice versa). If you’d prefer to share via a personal account, use the Cog > Share function after the post is published.
