In the Galleries, Portfolios and Articles sections, all materials are given with three icons above.
The first icon, Star, is to add the material to you Favorites. This is your bookmarks to the best of the site’s content, your personal collection of useful materials, i.e. photos, projects, discussions, etc. All that you mark with this star is visible only to you in MY – Favourites.
The next icon, Like, is to mark the material as good, and this mark is visible to anyone on your Activity feed, and on your friends’ feeds.
The third icon is five consecutive stars, which gives you the opportunity to mark the material in a five-mark grading system. The articles, portfolios and other materials take part in ratings, within the section they belong to.
