I know how people here feel about Honeymoon registries, but what about registering for charity donations?
My fiance really REALLY hates being given gifts. And especially "obligatory" gifts tied to special occasions such as birthdays and holidays. He really doesn't want our guests buying gifts and wants to request no gifts. I told him people will likely buy us gifts anyway and that we should register, but he refuses. So we thought maybe we could request guests donate to charities that are meaningful to us in lieu of gifts. is that tacky?
