Comment This is not THAT different from canadahelps.org (Score 1) 66
Canadahelps.org allows you to donate to any registered Canadian charity, if the charity has not set up a Canadahelps.org charity account, they just mail out a cheque for anything that is donated using the registered charity's registered mailing address.
A crucial difference is that Canadahelps.org is itself a charity, subject that the oversight that entails. I think it is a great value to the charities who use it since it can greatly simplify the charity's accounting and official receipt generation requirements, at the cost of losing out at a closer connection to their doners. From the point of view of a doner, it certainly simplifies things to have a single place to do all your donations, potentially combining multiple tax receipts into just one.
