Blogo allows you to schedule your posts so that they publish at a later date. It's really helpful if you want to aim for a specific time, or you like to write loads and then spread them out over a period of time.
Anyway, it's really easy. Just click on the calendar icon to the right of the Post's title, and you can select the day and time.
Once you've set a date for the post and turned "Schedule" to on, then the Publish button will now say "Schedule" and then you can just post like normal!
