Why not edit your posts intead of adding a new post again?
Anyways, when you log in with your account you can see the other example pages to see the code. Check the edit button at the bottom left, but
do not change anything. This is just to see the code so you can make one yourself. If you don't have any html experience, then I would recommend reading up on it a bit before you make a page.
There's wikki tutorial sites on the internet as well.
