We're looking into a whole bunch of ways to stop charging fees as soon as we can - it was kind of the lazy way out for the short term. We're looking into referral fees, as you suggested, as well as earning interest. We also had an idea that, since we know what a user is saving for, and roughly how long it'll take for them to save for it, we could put the item up to tender and hunt down cheaper deals so the user can save money. Just an idea, but there are so many interesting things we can try when we have that kind of data.

Re: pause - I totally didn't consider that, and smurfy brought it up too, so I'm probably going to build out a 'protect me from myself' feature to do just that
