Press enter to bring up the chat box then type your chat. When you have completed your comment or run out of room (the chat bar has a limit of so many characters) press enter to send your chat. Wizard 101 chat is filtered chat so if you use misspelled or inappropriate words the message will appear as "...". Numbers and names are also not allowed to protect the users privacy. Players under the age of 13 are also unable to use the freeform use of the chat window and must use the help bubbles to communicate. You can turn off the chat filter by going into the account settings at wizard101.com
