I just created my account today. At some point in the process, a page appeared that had a box to enter a title and a box to enter a post. I began typing and typed for about 20 minutes. There was a Finish button at the bottom of the page. I clicked it. When the next page came up there was no trace of my post. Gone, can't be found. I'm done playing with WordPress for today.
The blog I need help with is differenceofsquares.wordpress.com.
