Over the last few months I've been creating or expanding on several of the Tezuka-related entries on Wikipedia. About 40% of the main Tezuka entry is what I've written, just about 100% of the Amazing 3 and Marvelous Melmo entries, and I've done a few other things here and there as well, though there's still quite a bit to do. Probably the easiest thing is if I just post the URL for the main Tezuka entry here, then you can follow whatever other links you like.
