I just discovered a way to view all the posts created by just one individual. When you are in the posting screen, go to the "Labels for this Post" box, and enter your name. It creates a clickable link on the blog. Once clicked, you can see all the posts that have that specific label (your name). You can refer to any of my posts for an example.
Also, if you're not quite sure how to go back and edit a post you already made, let me know and I can do it for you (since I have this admin POWER that Bobi gave me).
Perhaps everyone already knew this, but I was excited to make the discovery... so just have to share.
