charity seems to be applied to all questions that somehow relate to charity, while two out of the three questions tagged with charitable-contributions deal specifically with tax issues. Should these be merged or left how they are? If they're merged, my opinion would be to preserve the more general charity tag and accompany tax issues with relevant country tags and the taxes tag.
I suggest we keep the charitable-contributions tag for those questions specifically about contributing to a charity, and the charity tag for anything else about charity not specifically involving making a charitable contribution. In other words, questions tagged charitable-contribution shouldn't also require the charity tag.
IMHO, I wouldn't want to lose the "contribution" concept by having one and only one charity tag.
Mind you, now that I'm thinking about it, why isn't it called
charitable-donations instead? What's the more idiomatic expression - a "charitable contributions" or a "charitable donations", or are they equally common? There are search engine ramifications.
