My Adventures in Technology - United Streaming

I signed up for United Streaming (Discovery Education). It looks like an amazing site. It has great videos that will be awesome to show my students on my SMARTBoard. I tried to link some videos to my wiki under my teacher resources section but I was not successful. My link kept going to the sign in page. My husband claims that he has linked videos to his wiki so who knows? I tried to find some resources today on the sight and was again unsuccessful because they were experiencing an unexpected error. I will try again later. Here is the link to United Streaming: http://streaming.discoveryeducation.com/.
