I would say it's a good idea to set up a link to their story site--if only to save time for the person searching.
ANd i don't think there'd be any need to worry that by doing so ppl wouldn't check the storyboards for new stuff- because not Everyone is gonna have an outside site set up, nor will they (prob) include a cross-referenced account of all their work so enabling the reader easier access to stuff would be great!
