Anyone can use DoNation. It's meant to be a bridge between charities and ordinary people who want to do good.
Only charities need to sign up to post requests. If you're just looking to donate, you can easily browse the current requests.
Charities who sign up provide contact information. We check to make sure that this information corresponds with the information posted on their website, and if there are any conflicts, we contact them via the information provided by their website.
It isn't. DoNation is free to download with no in-app purchases or advertisements.
