Content rating (PICS)
Type information in the Content rating (PICS) box to designate a Platform for Internet Content Selection (PICS) label that allows you to rate the channel based on its content. The server passes the PICS string to the chat client, which interprets it and allows (or prevents) access to the channel.

The PICS string, which is limited to 255 characters, is generated and provided by ratings organizations such as SafeSurf or the Recreational Software Advisory Council (RSAC). Visit the Web site of one of these organizations to acquire a PICS string, and then type (or paste) it into the channel's Content rating (PICS) box.
