Membership plugin for control access to integrated video tutorials

Hello,

Could you advise of the best membership plugin from the list of your existing plugins we can use to manage our helpdesk sign-ups? What we are looking to do is to have our customers register for an helpdesk account first before being able to access the White-label videos and support material we are providing?

We would first prefer to maybe display one or two videos that can be accessed freely and then if they would like to have access to all other videos and tutorials to sign-up first?

Looking forward to hearing from you.

Many thanks.

Regards
Anthony
