I am not sure if this has been requested before, but sometinmes I am looking at the showcases of different providers and I want to remember one or two, I wish there was a way that we could just click and add them to a "my favorite provider's list" TER has something similar. This way when I am on a specific city I can go through my list of favorites much faster.
You can add the person to your Buddy List to help you keep track of them.
Go to their profile, click on "user list", click "add to contacts."
