Well, now that Miiverse is on the 3DS, I thought I'd see if I could upload screenshots to the intertubes from the 3DS, but that doesn't appear to be an available feature. Not yet anyway. But I did find out I can log into Miiverse
right here on my PC and access my posts. It won't let you right-click and save attached screenshots but you can check the page source and find the image URL.
I got a little bored this afternoon!
Anime is kind of like fish in that it is better the less "fishy" it is.
