I have JiveTalk and love it, but can't figure out one thing. I can't see how to tell JiveTalk to ignore all inbound chats from anyone not in my contact list. Other chat clients can do this. Surely JiveTalk can too. I've looked on JiveTalk's website, but the help there is pretty thin.

I thought if you set it up on your IM client on your desktop, for example, Yahoo Messenger, or Windows Live Messenger, the settings would also apply when using those in Jive Talk. But I'm not sure.

On a per-account basis (your account, not a buddy), edit the account and select the appropriate item from Privacy Setting.
