That does clarify things, but users still have to go through several steps before they see it. When I look at your front page, the only impression I get is "web based group chat." You should elevate shared viewing to something you mention first.

edit: You do have the material for that, but it's under the "View Sites Together" tab. That information should be what I see first. Looking briefly at your blog, you understand this is your killer feature. You need to make sure your users understand that, too.

Thank you - Totally get what you mean - Will have a think.
