Entering Scores on Multiple Machines
You can use multiple machines for score entry, but you should nominate one machine as a master. The master will be used to make any changes to an event, flights or archers. The master will then publish the event to the Repository and the other "slave" machines will fetch that event from the Repository. The scores can then be entered on the slave machines (or the master), making sure that scores for a given archer in a given flight are not entered on multiple machines.
The slaves can then publish the event to the Repository.
Once all the scores have been published, the master machine should then re-fetch the event from the Repository to get all of the scores entered.
