No comment on the "200".
I do wonder if the connection/bandwith problems are the fault of the people trying to register as much (if not more) than the fault of the owners of the reservation system.
If your connection is timeing out because there are too many people trying to access the system at once using up the availible bandwidth....
And you "compensate" by trying to access the system though "4 different browsers".....
You are only making the situation worse by taking up 4 times as much bandwidth. You are actually increasing the time it will take you (and everyone else) to successfully access the system, and decreasing your (and everyone elses) chance of success at any given time during the heavy access period.
In otherwords, you are contributing to a denile of service attack on a system that you want to use.
Think of it as complaing about how long it will take you to get home from work during rush hour, so you buy 3 extra cars from brands you don't usually drive and try to drive them all home at once. Since there are 3 extra cars on the road (and 2000 other extra netscape, opera, firefox, and explorer brand cars from other people doing the same thing) the rush hour is more hellish than usual, and you end up abandoning 3 cars along side the road once you get the first one into your garage.
