They take a large slice of your charity funds for what? They are basically just a holding account. Their donations page then asks you for a 'tip' of at least ten percent (its impossible to donate otherwise), what a rip off. The only tip this organisation deserves is a rubbish tip. I found Just Giving to be useless at helping, sort issues with their site. Scandalous. Stay well clear and just set up a holding account of your own. This is a shameful barefaced way of creaming off money - lots of it, from peoples' generosity.
Just giving is very simple to use for charities and public fundraising. I have used it in the past. I would recommend Just giving
