It's funny you ask that, but I think I am a very good typist, so I don't really proof (ego)

. I do however try to read my post as soon as I post it, so if I see an error, I try to catch it before my time to edit expires

When I see one later, it bothers me.

When I see other people's posts, I try to read what they mean and not worry that they made a typo (that has actually taken practice, as I am a proofer as well.)

And I love smilies!
