Go to My Mibba and on the header bar, there should be one that says 'drafts'. I think the older drafts are toward the back. If you have private journals, layouts, or anything like that they'll be in the front.
I felt the need to say I LOVE THE NEW MIBBA!! I returned from a little hiatus to a new, clean, slick lookin' Mibba and I am lost but I love it. Thanks!
