Ed1Stop subscription was not renewed for the 2015-16 school year.
Teachers may still be able to log on until the subscriptions time out, and then connect to Discovery Streaming vidoes to download favorite clips and movies.
Another option is to log on directly to Discovery Education (until those subscriptions get cut off.) If the account was set up through Ed1Stop, the username is likely your district username, plus underscore solano as in barryr_solano. Contact Barry Rico for password resets to Discovery.
