How can I change the number of relays a team can enter?
You will have to delete and re-add the age group with the correct number of relays. In order to delete an age group, you will first have to delete the events that use the age group. You might consider only removing the relay events and adding another age group only for the purpose of relay events. You will not be able to remove an event if a team has already made entries to the event. If entries to the event haven't yet been submitted, you can removed them from the event, delete the event, change your age groups, recreate the relay event, then add the entries back to the event. You may want to turn the 'Meet Status' to 'Off' to prevent teams from potentially submitting their entries (just make sure to turn your entries back 'On' when you're done). If an entry to the event has already been submitted, you will need to create another age group and event, and direct teams to enter the alternate event instead of the previous one. It may be easier to manually accept the entries and payment outside OME.
