It is the big give. I haven't heard of them but has just 49 donations with only 3 days left and is thousands off the target.

Made me suspicious as if genuine its an organisation that provides great support and they've been involved in the campaigh with Mumsnet to get the new variant of the CSA overhauled and made to inforce powers so I wanted to donate.

I can’t speak for gingerbread but the big give is a legit charity thing that happens at this time of year every year for the organisations that meet the criteria and apply
