When work is done on race day, you can check the event file back in. Note that afterwards, you cannot access the event offline anymore but instead you need to log in again on www.raceresult.com to access the event.
So, make sure you are done with work when checking the file back in or be prepared to make last changes online.
To check in the file click Online->Move this Event to Server (Check-In). The upload may need a few seconds or minutes depending on the file size and the speed of your connection. The column Online shows the progress.
