I'd like to go. If I get the IBM Champions nod, I think it's a sure thing.
Lessons from last year. Get to the Cognos sessions early, and don't give up your seat for any reason. Bring a bottle of water and some sandwiches, and don't forget the brass knuckles.
For each of the sessions last year there were a few hundred people trying to get into a room with a capacity of 75. Hopefully IBM learned something and will give the Cognos people a bigger room.
