What are specifics of IRC chat and whispering (Noob) [SOLVED - I think]

[Freddy]

The format @TrainerTimmy listed is for incoming whisper. You want the one for outgoing whispers.

@madmanmike

PRIVMSG #jtv :/w [TargetUser][whitespace][message]

As you mentioned yourself, that is the correct format and the one @TrainerTimmy was refering to

@TrainerTimmy

But if you can’t send whispers with /w, try .w instead.
