If you are looking for a particular item related to a particular game, you can use a search bar. You will find this feature in the middle of the screen. On another hand, if you want to just explore the website, scroll down the page and see all published items. Right away on the bitskins.com, you will see some information about them: avatar, suggested price and more.
BitSkins's online platform also provides its users with the Chatbox section (on the right side of the homepage). If you want to participate in discussions, you need to sign up to the service. But if you do not interested in such communications, you can just close the Chatbox window.
BitSkins is a very open platform. You can contact not only its support team (via firstname.lastname@example.org.) but also the founder of BitSkins himself (on twitter.com/anazir or via email).
