As far as remembering flights, I'm not saying if you can remember where you've been, that's easy. I'm saying if you can remember details about the hubs you went through, equipment type, etc.

What to do on the site, you can create a free account and enter your flights, and it will tell you everything it shows on my page about your flights.

I just found it and thought its kind of cool and decided to share it with everyone here.
