It works like this. Someone organises the race and lays down the rules, which track, car, mods etc and sets a deadline.
The entrants go and run the race on their copies of GT3 and save the replay their runs. They them e-mail of PM the details to the organiser.
After the deadline the organiser collects the entries and posts the results.
OLR is a bit misleading since the racing is done offline.
