How to hide Konversation-Notifications at all?

Hi there

i am trying to tell Konversation to hide every notifications like "xyz
enters/leaves this channel" and so on...

I read http://konversation.berlios.de/docs/cfg-notifications.html.
I tried out a lot, but in my opinion there is only the possibility, to
make new notifications instead of hide an existing one.

can anybody help me?

regards, hag'n
