I'm trying to explain to both my father and brother how to set up a Sling account and add my Slingbox Pro HD to their account so they can watch it remotely as "Guest Account," where I provided them with a viewing password. However, there is no clear and unconfusing way to do this. Slingbox.com isn't very helpful in trying to explain how to do this. Is there some step-by-step guide I can either copy or write up for them in an Email?
I understand that you want to know if is there any guide in order to know how to set up and use a Guest Account.
