This command forcibly joins a specific user to a specific channel. The OperServ equivalent of this command is svsjoin. This command will open a new channel window on the target nick's client. This can be useful for bringing several nicks to a channel, perhaps for dispute resolution or to warn against undesired behavior. This command takes 2 arguments, the nickname to join to the channel and the channel to which it will be joined. To join nick1 to channel, issue this command:
/sajoin nick1 #channel
Note that users can simply part the channel again. This command will not keep the user there.
