Great question. When someone signs up for your comp and can't make it, they usually contact you as the organizer. You then have to go in and change a bunch of information once they find someone to take their spot. If you get more than a couple of these, it can become an administrative nightmare.
CompTracker automates these transfers for you. When you set a Transfer Cutoff Date, registrants can transfer their registration to someone else within their division. They simply enter their email on the home page to see upcoming comps and then click 'Transfer' on the registration in question. They will receive an emails with a unique code that they can then forward to the person taking their spot. The recipient clicks the link, enters the transfer code and the information is updated.
We also tell each party to handle the reimbursement of the fees between each other so you don't have to - nice huh?
