Blogger had a glitch this past week, and deleted some posts in the process. They are working on restoring them. So hopefully they will restore your soon.
Michelle, thanks for letting me know!
One of mine disappeared, comments and all. And a few friends' did too. Luckily I still had the email from when it published. I reposted it. I had to reload all the pictures but at least I didn't have to come up with text again. Whew. I saw that Blogger apologized for the problem but I don't know that they can fix it... we'll see!
