1) What functionality is available to add 'two-dimensional' lead source tracking -- for example, differentiating between Bing vs. Google Adwords searches as well as SalesIQ vs. embedded form?

2) Is there a 'round robin' functionality included with the team management, where multiple team members can simultaneously work together with a user?

3) Is there an easy way to toggle off the system, in the case that there is nobody available to chat?
