You can either leave a comment for the broadcaster directly on their channel page, or you can send them a private message in the chat room by clicking on their name and choosing ‘private message.’

To leave a comment for a broadcaster, go to their channel page, scroll down below their player and enter a comment in the comment box. Note: You must be logged on in order to leave a comment, and you can only leave two comments per channel per day.

The chat room allows anyone with a Ustream account to participate. The Social Stream allows users to log into their Twitter accounts from the Ustream channel page. If users don’t have a Twitter account, they can view the social stream but won’t be able to send Tweets. Broadcasters and viewers alike can use the Social Stream, and the feature allows users to Tweet questions to the broadcaster and will automatically generate a link back to the Ustream show page. Broadcasters can display both chat and the social stream features or one but not the other.
