What chat, in-game mail and Broker restrictions do Free and Silver players have?
Free members can’t use any of the “broadcast” channels, such as /auction, /level, /shout, or any other chat option that broadcasts to a large amount of other players. Silver and Gold members have access to all chat channels. Free and Silver players can receive in-game email, but can’t send any until they upgrade to Gold. Broker access is restricted to Gold members only.
