It's not over yet, but here's the findings so far:

Covers are very hard to find. I have at least 4 clan mates (kj,eddie, queenb, syan) that have all 30 pages, no covers. Many others have a few pages, no covers. I am the only one with a cover and I can't seem to get enough pages (currently 23/30)

Anyone completed this in time?
