Quoting Chris Phipson
ONLY those who are nominated for an award may add their creations and ONLY those creations that are nominated.
If you are nominated for a "personal" award (such as YFOL of the year or any of those others) then you may choose one moc from your page to add.
I've been nominated for "Most Improved" (Which by the way I feel very honored and grateful about), so I take it that counts as a "personal" award. Just checking before I add any creations.
