This might be a little bit premature but I would like to hear some ideas on how the organizers of a theoretical C4 could make things better.

Here are my thoughts:

1. Selling of merchandise: It would be nice if you could pre-order online if you are a fan club member. Then, you can have your choice of either picking up there (online prepay) or having it shipped to you (instead of carrying this stuff around all day).
2. The full detail of lectures ahead of time. I always find out about who and what is speaking and at what time when I first arrive.
3. I would like to see an offer of either DVD or online webcasts of entire presentations that I couldn't make. It would have been awesome to have seen the collector panels or the initial parade.....

So, what are other ideas?
