Does This Plugin Require Users to Sign Up, Or Can They Just Be Guests?

Sorry to bother you guys. I am using the Avada theme, I’m not great at this stuff, but I’d like to be able to install a Favorites plugin that allows potential customers when surfing my live bands’ pages, to be able to “like” a band page so it gets saved in a shortlist for them with any other band profile pages they’ve liked, and then have the functionality that they can send me that completed list, along with any text questions they might have, when they are done. Can this plugin do that? I also don’t want them to have to sign up just to like some of my pages to send me. I’d like them to just be guests with favorites functionality.

Thank you, Stuart
