With all the mistakes I make, you'd think I never got past third grade. The best thing to happen to me especially on this site is, thanks to you, Ispell (and as you so wisely pointed out even it doesn't cure everything...yeah, I too am forever making the their/they're error).
One can't really proof read their own work and all of my newspaper columns I submit for publication, I save. When I go and draw them up for one reason or another, more often than not, I'm embarrassed to death. Thank God they have the world's best editor at the paper!
