Re: $25 Donation
Although you wanted this thread to be locked, may I add something from my personal experience?
When I went to donate for the $50 donator status, I sent about ~$55 canadian as a money order to Matthew. About 5-7 days later, he checked his bank and they had received the money order. Now before I sent the money order, I had talked to him about fees and whatnot, and he informed me there will be a minor ~$5 fee to convert the CDN to USD. Although it is nowhere near his fault, the fee was not $5.
Long story short; he didn't take it at that time, but out of pure generosity he asked if I wanted it sent back to me, due to the amount of money I would lose from fees plus the conversion rate. I asked him to just convert it, and I was okay with what the outcome would be.
Turns out, I lost ~$19 in fees. So I ended up with a $36 donation. I would highly recommend converting your AUS currency to USD before sending money, if you ever do. I noticed you wanted to do it by WU, but this is just a recommendation if you ever want to send Matt a money order.
