Plural: crimebusters IOUs
Personally, I blame the IOU for opening the door to all of the other horrible spelling and grammar on the internet. After all, if IOU is perfectly acceptable as a replacement for "I owe you" then why can't the phrase "can i c how u do dat 2?" not also be considered valid? Where do you draw the line and call one "acceptable slang" and the other "a sign of ignorance and laziness"?
"Wherever you want," I think, is the right answer.
