Facebook made some changes to their “Pages” which you can put to work for you now.
The changes are in the Admin section and in the timeline posts.
When you edit your page and choose “Admin Roles” you now have 5 ways to designate helpers on your page.
The other thing is the option to ‘post date’ messages to your Facebook page. You start in the page. Click to create a new message. In the lower left, a clock appears. When you click on it, you pick the year, which reveals ‘month’ then ‘day’ then ‘time’ and wait for your post(s) to appear. I’m testing this myself.
