I may have missed the option in the BLOG's menu of features, but I do not see any options to schedule a future post to publish or for that matter "unpublish" on a certain time & date.
It would also be really cool if the feature allowed you to publish / unpublish posts for repeated comments to automate such types of content ...
Wordpress has this feature already. Which is really, handy if you are going beyond the post and forget it type of work methodology.
