User blog:TarantellaEarth/Episode summaries?

I don't know if this is the correct place to post this, but I've been wondering this ever since I started using this wiki...like, four months ago. Where do the mini-episode summaries come from, the one-liner ones that are put on the episode list weeks before they air? Is there something similar on the actual, Japanese, Hetalia website, and someone who can read Japanese is kindly translating and passing them over here or do we have our own secret source or...?

Just curious ^^
