In my time on joeuser, I have never seen this.
What I thought was just a glitch on my attempt to post a story on a burrito being mistaken for a weapon, has apparently wrecked my blog. All I did was copy/paste into the text box, and now my site is ruined. I am hoping admin can delete the article, because I have no delete options appearing on my screen.
Oh, for an "undo" button.
