Describe can be used to express how a person is feeling or what they are doing. Quit logs you out of the chat. Currently the server automatically flushes any messages more than 2 minutes old but messages can be flushed early with this command. Depending on the font size or what time of browser you are using, the display can be improved by adjusting the number of lines that are shown in the display. Also, some users with many private messages find it better to reduce the number of lines.
Messages can take more than one line.
If you want to change your nickname without leaving the chat you can use this command. If the nickname is an Operator reserved nickname, someone else is already using the nickname, or has recently left but not expired from the database, the nickname change will not be allowed. The help is divided into two sections, the second for Extended Operator Commands. In some cases the options are required in others options, and some commands have no options. Substitute your own options in place of the bracketed values.
