It acts as a pre search, along with age range preferences, so that members only see, and are only seen by, other members who they are likely to find attractive. This community-based system is one of the site's unique selling propositions in that it allows a more nuanced search function for attributes within user profiles. Members can then choose to allow or disallow other communities from being able to see them. Members join any of several communities such as those reserved for those that are visibly muscular. There is a space on the profile dedicated to a text description of the member and what he is looking for, these blurbs range from a few sentences to full pages. As a result, the site has been described as the most graphic and audacious of the gay dating sites. They also upload pictures of themselves, at least one of which must show their unclothed body, shirt off. Members select various statistics which include, race, age, height, weight, adherence to safer sex practices, amount of body hair, body type, penis size, and other criteria.
