Think think think before you send. A silly, little grammar error could spell deal breaker for you. Watch out for the dreaded 'irregardless. ' it's not a word: don't use it... Ever. And while you're thinking about all those picky points, consider the difference between 'less' and 'fewer. ' use less for mass nouns as in: 'i have less money than you. ' fewer goes with count nouns: 'you have fewer coins than i do. '
