This is an often overlooked feature of the site. While we are the place for the highland games, the games tend to bleed into and overlap with other things. How many of you have had a 10 event while the judges are tallying scores? Sure it may not count but wouldn't you like to have a record of it? How many have done a highlander competition? What about stone lifting? Or maybe your game was at a brewery and the AD added some keg events.
ADs have the power to add any and I do mean any event to their games. For reference just check out these:
Any score entered into a custom event will show up for that game and only for that game. Scores entered in custom events do not effect rankings.
