New Blog view-
I'm feeling like Alice in Wonderland.... my blog is out of control!
Not sure how I ended up with this new version of my blog. And I don't know how to change it back.
I am going around in circles right now trying to find my layout/ page elements tab to change things. I'm supposed to go to my dashboard to do this, but I can't seem to find the tabs I'm looking for: Postings/ Settings/ layouts...
 This is quite frustrating....  :(
