Posting in the Future on WordPress

I can’t believe I didn’t work out how to do this until this morning, but if you want to write a post in WordPress but not have it show up until a later date or time, all you do is edit the timestamp on the post to the future time and hit publish. Job done.
This could mean you could focus on one blog for a few hours while you write loads of posts then move on to another job but still have your posts appearing at regular intervals for the next week. Now I know how these guys keep blogging while they are on their holidays. Doh!
PS This post should be appearing at 1am but I will be sound asleep by then. I hope.
