Allow members to prepay - and apply credits toward events
Some of our members are unable or unwilling to use PayPal or Amazon Payments. On the door payments are an incredible hassle for the organizers so we charge more. Further we then have to reconcile the fees.
It would be nice if a member could give us a cheque to cover multiple month's worth of events, such that we could apply the credit to their event account, and meetup would debit this balance every time they attend.
