Our company has converted client training to nearly 100% virtual classroom (live). We use GoToTraining now and would like to experiment with some others to be diverse in our offering and delivery to meet the needs and prefernces of our clients. We prefer a system that allows students to register and pay online in advance. We also want to use cameras, upload documents, and use quizzes/polls/whiteboards. Please post some of your experiences. Thanks in advance.
