I'm in a hold pattern. After spending an hour attempting to register for Ironman Wisconsin 2007, the closest I got to actually completing the process was an error page after clicking "Submit." Half of the registration process was completed, as I received an Ironman ID from the system.
Unfortunately, the important half seems to have failed. There was no confirmation, and IM Wisconsin doesn't appear on my list of events. I sent an e-mail to Active.com asking about the situation, but doubt they will have much leeway to help out. After weeks of agonizing over the decision, it is distressing to be shut down by a system error.
If anything changes, I'll let you know.
