From the NextWeb original article: "Facebook is continuing to beef up its offerings to Facebook Page administrators, adding features that were previously only available in third party apps, with the latest allowing them to assign administrator roles and schedule posts.
Page administrators will no doubt appreciate the ability to assign specific roles to other admins.
There are five different categories now available on Facebook. In descending order of the most permissions, they are Manager, Content Creator, Moderator, Advertiser and Insight Analyst."
"Facebook administrators (with permission to create posts) will be able to schedule posts up to 6 months in advance, with the ability to run posts at least 15 minutes apart.
All times will on these posts will correspond to your own timezone.
The feature, while still not available for most, will be accessible when creating a new post.."
