Just sent you all some invitations to the ning network we'll try out to replace moderator (you're right that left a lot to be desired) as a discussion forum. You can post text, images, and video on it.
I hope you folks use the forum to discuss homework and lectures, e.g. posting buggy images from your code, or buggy video, asking for and giving pointers about XNA, posting stuff about lectures, and just telling us about cool stuff you find.
You should be able to join with your ncsu IDs.
