Usage: SAJOIN <#channel|all>
This command will allow you to join channels that are locked, keyed or have bans set against you. You will also not be able to be kicked out from any channel you entered with SAJOIN. When you use the command 'all' at the end of this command you will be joined to all channels on the server (max 100).
/sajoin #test
/sajoin all
If the people running a channel are causing problems and they try to ban you when you are discussing this with them, then you can force your way in so that you can explain what you are doing. You can also use this along with SAMODE to op yourself in the channel and remove anyone who is misbehaving. This command can be used simply to make you unkickable.
