zomg, i'm not even being sarcastic!
http://www.chinesetopinyin.com/ i'd been messing around with an old musty chinese dictionary i think i might've been allergic to, but this is so much more efficient and helpful for everyday use considering my needs. to think it required only a simple google search. i might actually learn how to write chinese now!
i wish, though, that they'd use intonation marks instead of numbers.
EDIT: nevermind, i found that too. :)
