There are lots of different ways to get your channel discovered or to give yourself that extra bump. Here are some of the features we have at JTV to help that.
If you click on the "Share" link underneath your video pane you will see a list of features that you can use to promote your channel. From this panel you can send an Email to your friends and submit your channel to various social bookmarking sites.
Or lastly from this area you can invite your friends from your email address book or your MySpace account from your Invite Friends tab
