Site registration and gallery share

Hi,

This seems like a fairly complicated endeavor, but here goes!

I use my site for my videography business. Much of what I do ends up online. My clients can then share the password protected videos with whomever they choose.

I was wondering if there was a way I could make the client register first to access their gallery and then generate their own email list to share the videos with. Those individuals would then also have to register to view the gallery.

I’m thinking this would be a good way to generate a longer contact list of prospective clients. The way it is now, anyone with the password can anonymously watch my videos without any way for me to reach out to them.

Any help would be much appreciated!

Thanks a lot!
