Once again inspired, or at least reminded, by one of Lenn's (Pitchy) posts, I realized that I had quite an assortment of "leveling devices" to which I'd never previously assigned the moniker of "collection", as I'd always consider them to be associated parts of other collections that I have intentionally made, but thanks to Lenn, I may now appreciate them as collections in their own right if I so choose!
