Sorry if this has been posted before, but Nickelodeon has made full episodes of shows available to watch streaming on the internet.
http://www.nick.com/all_nick/turbonick/ If you click Nick Rewind, it has the classics: Alex Mack, Clarissa Explains It All, Pete and Pete, etc. Do you think if we emailed them enough, they'd put up Space Cases up for the "now" generation to watch?
