Do you know about Draft Blogger? I'd never even heard of it before today. I think it is their beta testing environment, but it has at least one cool thing that you can use at the moment - and that is scheduled posting.
Basically it means that you can write a whole bunch of posts and then schedule when you want them to appear on your blog, and it's easy as to do!
If you still want to use future dated posts that show on your blog, that's pretty easy to.
I really should pay more attention to what is going on around me I guess!
