Hi marketingfrosting,
Well You can use the following plugin for this purpose
WP Favorite Posts
It Allows visitors to add favorite posts.This plugin use cookies for saving data so unregistered users can favorite a post. You can choose “only registered users can favorite a post” option, if you want. Also there is a widget named “Most Favorited Posts”. And you can use this template tag for listing most favorited posts;
Hi CrusaderX3,
Thanks so much. If you know of any other plugins that give a signed-in user list functionality, I would love to hear about it. I’m also looking for a Ta-da list/don’t forget the milk type function. Thanks again!
