UG has over 12 million registered users. It is a strong community of forum users who frequent the site. The website is regulated by an administrator and moderators, who are privileged members who can edit and delete other users comments. Moderators are users that are rewarded for being particularly helpful and knowledgeable in a specific subject and are responsible for moderating forums that focus on the subject they specialize in. Inappropriate words used to be censored by a computer that searched for and replaced undesired words posted within the community, until September 1, 2015, when censorship of curse and swear words was lifted on the website. Community members may also create guitar lessons, and have their approved works published on the website and read by its users. Reviews of albums, DVDs, or gear and news articles can also be submitted by members.
