Tell TV Land You Want JTTOU
I think TV Land still has the rights to the show. They air it occasionally, not recently but they have in the past.
Go to their message board, click on "programming suggestions" and tell them you want Just the Ten of Us. Either on TV Land or Nick at Nite. It doesn't matter as long as they air it. If they start airing it regularly we might be able to get it on dvd. Do what you can. Email them and post on the board. Maybe they'll listen. Reruns are better than nothing at all. Show them you're interested!
Here's one place you can let them know.
