Sites should be of significant interest to users of file-sharing software, with news, discussion, or reference features. Sites exclusively focused on a single network that has its own subcategory (e.g. Gnutella) should go to that subcategory.

Please note that if the site is offering storage on the web, it should be submitted in Computers/Internet/On_the_Web/Web_Applications/Storage or its subcategories and not here. Keep in mind that suggesting a site in a wrong category may considerably delay its review.
