Chat is a feature that allows near-instantaneous communication between users on a wikia. Anybody with a Wikia account can join chat by clicking the "Join the Chat" or "Start a Chat" button below.
Private messages are conversations between you and one other user. If you are in a private message room with someone, you have the ability to stop receiving their private messages by selecting "block private messages" in their username menu. This setting is permanent and Wikia-wide until you select "Allow private messages" from their menu in the general chat room.
A feature in chat, borrowed from IRC, is the "/me" action. If a user (for example: YourName) preceded an entry in chat with "/me", it would render specially:
/me is going to the movies.
would appear as:
- * YourName is going to the movies.
Links work exactly the same in Chat as they do in the editor. For example, typing [[Special:Forum]] in Community Central Chat results in Special:Forum - the main forum page of Community Central.
You can make shorter links to other wikias by using an interwiki link. For example, typing [[w:c:starwars]] in Chat results in w:c:starwars - an easy way to link to Wookieepedia (http://starwars.wikia.com).
You can also link to specific pages using this method. Typing [[w:c:avatar:Aang]] in Chat results in a link to the Aang page on Avatar Wiki (http://avatar.wikia.com/wiki/Aang).
