I'm testing the theory that I explain below. If it works then this post will appear as if I wrote it a few years ago, when, in reality my blog has only existed for half a year.
The reason behind it is that you can only create 10 pages in blogger-including the main page. So, what you do is after clicking down the advanced post options you can schedule the date you created the post. By doing this no one will know that the page is just a regular blogpost, and you can put it down as a 'contact me' page or 'about us' or whatever you need.
