I want to add a passworded channel to my autojoin script, but join #channel pass is not the way to do it.

I found this post https://forums.mirc.com/ubbthreads.php/topics/242744/Autoconnect_and_autojoin_don%27t#Post242791

But that does not seem to do it, either.

Can anyone tell me how to add a key to a channel in my autojoin script?

Have a look into this website you will find a lot of remotes with your request: http://hawkee.com/search/autojoin/
