Aria and Saki (and similar series tags)

Hello. I have an account here on Danbooru but I use mainly Sankaku Channel, which reposts some posts from here, as some of you might know.
Anyway, some time ago, I created separate tags for the series Aria and Saki (aria_(series) and saki_(series), respectively) since the tags aria and saki are also used for other stuff.
Since, again, SC reposts stuff from Danbooru, I'd like that to be implemented here too.

I don't see the reason to move aria and saki to ambiguous category, and I certainly don't think we'd do anything just to make reposting easier. If other sites resort to automatic post grabbing, they should know better than to copy tag list verbatim.
