Any which way that works for us living outside the U.S. Paypal, VISA or simply sending money to a bank account. A donate button on the AGD website would work as well. If there is a concern over not raising enough, and having the hassle of refunding, why not simply quote the sum we're aiming for, and extend the poll here on A.O with sums people are willing to pledge. In my mind the vast majority on this site are responsible adults, whom we can expect to own up to their pledge, right?
