How do we know if a tip we submitted is approved or rejected? Do we receive an e-mail? Also, how long after submitting a tip does it usually take to be approved/rejected?
That doesn't seem related to Mr Bowtie's query about fuelly tips!
As far as I know, it's up to us (the users) which way around we do it (and indeed, to decide what is actually 'city'). But I think most of us use a % of miles.
