/Ignore and /delignore Commands

[Joggin]

I've just been testing these two commands ingame with someone.

I can /ignore [id] him and when he tries to send me an in game message all I get is a date stamp, But when I try to reverse this by using the command /delignore [id] I get an Error message saying "Invalid ID" . Yes, I have checked the id spelling very closely, so there's nothing wrong with the way I am formulating the command.

Can anyone throw any light on this?

Does the /delignore work? Am I using the correct command even?

Thanks for any ideas/assistance
