Any decent free font managers?

I’ve got a mess of fonts that I’ve downloaded from those crappy free font sites, used exactly once, and then left to clutter up the system. There are some worth hanging onto though, and I can never remember their names when I need to sift through the crap and find them. Any suggestions for keeping them organized?

adobe font manager used to come standard with some products. you could enable/disable groups of fonts so that your font menu list would not become cluttered with 1000 items.

I second The Font Thing. Still useful six years later…
