i never typo.
*I. .

I make a reasonable number of typos from rushing my typing, but I always go back and correct them, as best I can. Chatting, I don't watch as much, unless it's really bad. If I typo in a post and don't notice until after I submit it, I'll go back and edit it. Sometime's I'm fast enough to escape the embarassment of the "Last Edited" tag .

Preview Post helps a lot, too.
