I think what you are thinking of is the eye witness forms. You can still use these if you want, they are the
Alternative Witness Method
The current preferred electronic submission method is outlined on this page -
Documentation Guidelines
Please take the time to read thru the BBG1500 page and re-read the SS1K rules to ensure a smooth submission too.

If you opt to do the electronic submission method, it's a really good idea to take some test photos with your bike to make sure you have a way to get a clear odo/receipt combo shot in varied light conditions and in the dark. Some digital odometers can be a real challenge in sunlight. Not to mention having a way to hold your receipt in place so the wind doesn't blow it away when you take your pictures.
If you use the alternative witness method, remember that you don't need the start eye witness to witness your odo at the exact moment of your start. If you're starting at 0200, it's fine to get someone to verify your odo the night before.
Same with the finish odo eye witness. A reasonable time and distance is fine. Your starting and ending gas receipts are the official start and end times. The eye witnesses are just verifying your odo before and after the ride. If you get finished at midnight, you don't need to wake someone up. Get the hotel clerk or your wife, etc to verify your odo in the morning. Especially if your morning location is a short distance from your finish gas receipt location.
Remember that it's your responsibility to make it as easy as possible for the IBA verification teams to follow your receipts and see that you rode the route you say you did w/o any possibility for short cuts. That's why you document your corners and turn around, if used. Any electronic dated business receipt with all of the required info will work. Gas receipts are easy, but any solid receipt does the job.
