I'd like to suggest being able to donate via phone.
(Having different numbers for each subscription. and being able to text or ring, so people can use the credit on their mobile phones.)
I'm only 15, and I don't have a credit-card/paypal, and I'd really like to donate, but my parents are a bit screwy when it comes down to the internet and money.
I don't know how it could be done, I'm not too great when it comes down to computers, but I know its possible, as its how I used to pay my subscription to RunehateScape.
If this is ever possible, could you also make it so europeans can donate via text or ringing? (I'm from the UK, you sees. )
Sorry that I don't know more on this subject, but I think more people would donate if this was to be put into place.
