Popup Stack Suggestion


On a car enthusiast website, I have a page that is “locked” using the “Locked” stack by Yuzool.
They would like a popup reminder when you click on the page link “Members Documents” to remind them that a password is required and a password hint. I have yet to utilize any of these stacks so I’m looking for suggestions. This is an older group so I’m trying to keep it as simple as possible.

Thanks for your help in advance.
