The video feed would quit with the error notice " content not available". One had to reopen My Account and start a new video feed, where the lecture was on-going. The first time this happened I waited for the lecture to continue. When I did not I re-opened My Account. This was frustrating. I missed content and also the opportunity to validate my attendance with the random "check mark". This occured four times. The last time at 4:12 and 4:41 p.m. EST in the "Ethics" presentation. Mr. Silverman's presentation jumped between the outline in his materials and his more detailed materials. Presentations are more effective when the materials flow with the content. Ann Larkin's presentation tracked her power point and the printed materials. Ann Larkin reference her email "in the materials". Would you please provide her email contact as it is not in her "bio", the materials or the brochure.
