Yay a Red Dwarf thread! I havent heard anyone mention Kryten yet
(my personal fav). Robert Llewellyn has his own youtube channel which he updates regularly
http://www.youtube.com/user/bobbyllew and his own website with his own web series car pool on his site
http://www.youtube.com/user/bobbyllew. The vids are always entertaining and he often talks about red dwarf, escpecially the new episodes they're making
