A little late, but I've wanted to be a beta tester and didn't know how to get started. I've 2 macs (G4 and 7500 with a 233mHz G3 processor). I don't have references, but I'm getting ready to start selling textures. I don't have any intention of getting into modelling for a couple of years (at least), so I'm hoping to build up some contacts to do testing and maybe provide extra textures, etc.
