1 I'm not sure. If girls go up,, the thread would need to be renamed,, Perhaps going into negatives it is. Unless starting a new thread is necessary.
It probably wouldn't be fair for the girls to use negatives because that's extra to type. How about starting at 500 again? Can anyone think of a way to make it more challenging?
I'd say starting at 500 again is fine, i'll have to think about a way to make it more challenging other than getting your guy friends to join for this thread :d
