How to Favorite a Project
To favorite a project, a user selects the grey star button.
Once that has been done, the favorite button will be replaced with a yellow star and the number next to the star that represents the number of favorites will have changed by 1, which when clicked again will remove the project from the user's list of favorites and the star will revert to a grey color.
How to View a User's Favorites
In order to view a user's list of favorites, a person simply has to visit that user's profile and examine the row of favorited projects. The full list of somebody's favorites is available by clicking 'view all'. However, it's not always necessary to click the view all button to see every favorite, though, because some users have favorited few projects so all of them show up on their profile.
