I like the setup but I am not familiar with the old one. What would be nice to see is the option to add rewards that are not monetary such as trips or extra privileges.
I love the bonus/demerit points feature and I love the way you have it set up because it allows me to be specific about demerits and bonus points and why or how they were gained/lost.
I think that adding or editing chores is a little bit tedious as for some reason the days you schedule the chores for seem to change themselves sometimes but my overall opinion of the site so far is "It's great!".
I would love to see more reward options in the future though such as non-monetary rewards.
