Hi, McF. Nice to see you here! :-) Well, it's really up to you which Zone you compete in, as long as you enter in only one Zone at a time. If you feel that you can already compete in Zone I that's fine, too. Sometimes, it also depends on the monthly theme for the Challenge. For example if someone who usually competes in Zone I is not really adept or lacks experience with the current theme, s/he can choose to post in Zone II. (*
