Just wondering if it would be possible to create groups? I was telling a forum I am part of about fuelly & it suddenly came to me that creating a group where we could all see how everyone was doing could be interesting. I know we could just all add each other as friends but this way a new person would just have to join one thing to get everyone.
Another echo ... groups would be great because I can get more people to join up if they feel a sense of camaraderie about the whole fuel-logging experience, and get competitive about it.
This is why I wish there was a top-10 (for each car class) etc, but I realize (your concern that) that folks would tamper with numbers! Perhaps throw in some statistical metrics - minimum 25 fuelups, reasonably/evenly spread apart, no deviation greater than norms etc etc.
