The manner in which one uses ustream varies between the viewer and the broadcaster.
Most videos on ustream can be viewed or acessed by a viewer by simply visiting the website and searching for a video with a topic that intrests them. The viewer can then watch a live video or a prerecorded video. Live videos are the true advantage of ustream becuase they allow viewers to post comments live, as the video is playing. The video does not have to be live to comment however. Comments can often be made without having to log in, however, individual broadcasters can choose to have comments only be allowed by registared users.

Making an account is really easy. Like most online accounts all you have to do is create your very own username and password and then continue to fill out some personal information such as your birthday, gender, and counrty of origin.
