I've donated through it and used it as a fundraiser. No problems from the back-end as a fundraiser.When donating though, the process for what name one uses (for public display) and staying anonymous are ambiguous. Also the option to avoid paying extra to cover costs is obscured. I found this awkward as some people gave me cash for a fundraiser and I wanted to pay that amount into JG (from my own card) without any extras else I'd be out of pocket. Took me a while to work this out.
