Q: How can I give my thanks to the FMA creator for the last 7 years (9 for manga) of awesomeness?
A: There is no appropriate thread and I sadly found out at last minute (5hrs left until deadline, closes at midnight at 7/7) to have to bug a moderator, let them make it and then let others send their messages, but for those who wanna try their hand at Japanese and writing to Arakawa herself with a word of thanks, you can do so here:

(Not sure if they'll accept English only messages, but if she does get them, then I'm sure she'd appreciate it nonetheless)
