Hey, I can iChat videoconference from my computer to others, but not to my mom's, and I need that for when I'm in Ireland. Can someone tell me what the settings EVERYWHERE need to be set to in order to videoconference on her computer. I can't screen share to it to fix them myself, either, so I need to know what to do there, too. It might be settings on my computer, as well. Could someone tell me what I need to do to open the right channels to videoconference and screen share? Thanks.
