I have created two binders for just my smaller player collections. One for my Rox and another for everyone else. I even made cool cover pages. (Yes, I'm a dweeb.)
Finally, I believe I'll be adding a third binder of cards I deem as "cool". What does it take to be "cool"-worthy? Good question, but when I see it I'll know. This idea is still in the works, though.
In the meantime, I've posted these cover pages to my PC's page. If you've got some cool stuff of any of these guys, hit me up. Just because their in a binder right now doesn't mean they can't graduate to their own box someday.
