I would like to request the following new sub categories for science fiction collectibles.
Collectibles -> Science Fiction -> Doctor Who
Collectibles -> Science Fiction -> Star Trek
Collectibles -> Science Fiction -> Star Wars
Collectibles -> Science Fiction -> Buffy
I think it would make the whole sci-fi collectibles thing more usable as at the moment you need to pick choose when to put things, whereas fans of a series tend to be interested in all the stuff in one place.
Just an idea . . .
