1st page = intro video with optin to get more
2nd - 4th = subsequent videos with facebook comment section, but no optin
The pages are released over time via an email to those who optin after watching the 1st video.
My question is this: when people watch videos 2-4 and add a comment which is posted to facebook, their friends who come to investigate that page won't need to optin and I won't capture their email... they can just watch all the videos released to the point...
Is this the way people normally do things... not worrying about capturing emails from people that arrive from facebook directly to the later video 2-4 pages?
