The good news is, I have some video of an RS6 leading Friday's Speed World Challenge at Sebring: 4.23 MB, about 15 seconds. Quick Time.
The bad news is, I have no idea how to post it here. Guess I need a "host," but I'm no genius about these things. If it's simple and someone can help, let me know ASAP -- preferably before I leave Saturday afternoon for the "12 Hours," which will put 85 miles between me and my high speed on-line capability.
