On one of the account settings places in etools, they have a way to change your weight day. You can set it anytime you want, and it will start the week over then. I think it's in one of the menu choices when you've got the actual etools open, when you're tracking.
I'm over in Topeka, and I go to the mtg on sat morning! Do you go in topeka or Lawrence? Wouldn't that be a riot if we went to the same meeting??
Good luck!
