When umpires are under the age of 18, they are not allowed to request or self-assign to a game unless they are about 2 years older than the players. Consequently, if an "I'll Take It" or "I'd Like It" button does not appear next to a game, it may be the software has detected you are too young (it could also be your strength rating is too low, see Setting Comfort Level). If you feel that you are able to handle this level of game, then contact your Umpire Coordinator.
