For events where there is a team element, if a rider is a member of a team, the team colour is shown on the Recent Rides page.
As of approx. 5.15pm BST (4.15pm GMT) today (28 August 2007), the site is keeping a record of rider's previous results. Not copies of the run files themselves, just the ride times and ride stats. So from now on when a rider uploads a ride for a round where he/she already has a time, the old time will be archived, whereas previously it was just overwritten with the new time.
At present, the only place you can see any evidence of this is on the Recent Rides page, which now has an 'Improvement' column showing the difference between the previous uploaded time (if there was one) and the most recent time.
It's difficult to get any more information on the results page itself, so what's probably going to happen is that the archived result info will most likely appear on the ride details page in the not too distant future...
