You can schedule as many posts as you'd like and the system will take care of it for you.
If you go to Curate > Manage Content and in the Actions column you'll need to click on the little drop down arrow.
When you click on Manage Schedule you'll get the Scheduled Actions screen.
Here you can set the Action to Publish, Queue or Disable.
Once the Date section is clicked a calendar will appear and you can select the date and time.
The Time Zone is corresponding to the date and time you've selected.
Once you click on Add to Schedule it will schedule your post.
If you'd like to remove the scheduled post just click Manage Schedule again and you can click on the cross to the right of your scheduled action.
