"Touhou Project" and "Touhou" series tags

I've posted this on several touhou related doujin, and I think I should just mention is straight up here. There are two tags for the same series, and it separates the searches. I have no idea why, but I would definitely think it would be understandable that the two tags be merged into one (either touhou or touhou project). We are still seeing a bunch of tags jumping back and forth between the two, and it'd be nice to have 'em all compiled as one.

Comments?

There's this problem with some artists too, I believe. If I remember correctly, there's a Karma Tatsurou and Karma Tatsuro. Either way, I agree that these kinds of situations should be fixed. "Touhou Project" would probably be best or, at least, the most "official".
