got a webcam .. now trying to do video chat

using trillian or msn live messenger ?? how do i do it .. in msn live i can setup my camera and see myself in the setup .. but how do i go about doing a video chat ??

on Live or msn messager you have to invite the person you are talking to, it's on the side menu on the chat screen, if you can't find it take a screenshot and I'll point you to where the option should be.
