Do Users HAVE To Sign Up, Or Can They Be Guests?

Sorry to bother you guys. I need a favorites, or bookmark kind of plugin to add to my Avada themed site (my site isn’t Woocommerce – it’s just a regular website), that can give people the option to favorite any live bands on my webpages that they like the look and sound of, then when they’re finished looking at our bands, send me the list of their favorited bands, along with a message for me that they can add to their short list, like e.g. what date they need the live band for, where their wedding is etc.. just basic data form would do? Can this plugin do these things, generally? I’d also prefer that they didn’t need to sign up – I’d rather they just be guests.

Please let me know?

Thanks,
Stu
