Allow me to track pre-registration, hotel, and travel confirmation numbers for each convention so I can keep them all in one place.
I sometimes forget what cons I've booked a hotel for or have already booked flights to get to or if I've pre-registered or not. It would be nice to be able to track this. ...and while I do so, keep confirmation numbers in one place so if there's a problem checking in, I can just look up the confirmation number on the site!
If there is enough support for this idea, we can implement it.
