@Lorien: oldies are goodies. It's probably time to bring some of those back!
I might be repeating previous responses...sorry. I love the ideas of template pack, overlay theme pack or elements. A "CU to share" challenge (perhaps even a permanent share thread) - where designers create CU items to share with other designers - even if the designer wasn't artistic, something like a stacked flower or graphic element template would be fun to share. Plus, it would add to everyone's stash. Something to help designers stretch and create new things, instead of falling back on safe favorites.
Jumping off this, perhaps designers could post a mini-tut / youtube over in Tutorials when someone spots a paper or element they really admire and requests a possible tut. This would help us all learn new techniques.
