Good point Cricker, for those that have a webcam but maybe haven't used it in awhile, you might want to turn it on and make sure it works ok ahead of time
A few more bits of info...
The video chat will be like a chat room, where you can see everyone that is in the room with you. When you log into the chat room you'll create a username, I'd suggest using the same name as your SA account but it's completely up to you. Ike will be there, his username will be either Ike Taylor or Ike Taylor 24. Nobody else will be allowed to log in with that username.
When Ike clicks on your name in the chat room he'll be able to see you on your webcam, and when he is talking with you you'll be able to see each other. If you click on his his name at any time during the video chat you can see him
If he is talking to someone else you can still see him by clicking on his name at any time but he can only see the person he's talking too. He'll answer a couple questions from each person and when he is ready to move on to the next person he'll let you know. Ike will be the one initiating the conversation with each individual person as he goes through the list of everyone that is in the chatroom.
He is very personable and easy to talk too, and loves talking to the fans so think up a few good questions to have ready and lets have some fun!
