I’m a big fan of Lifehacker and all their little tips and tricks. Sometimes they’re obvious but the times they’re inspired well makes up for the rest.
One that you guys may find particularly relevant is an instructional note on how to track your customer service issues using e-mail.
Anytime I speak with customer service, I make a note of the rep’s name, what was discussed, and any other details (confirmation numbers and the like) in an email I send to myself. In the subject line, I list the company name and the subject of the conversation (Chase: July Phone Payment, for instance). I keep all of these emails in one folder. I won’t ever need 98% of these emails, but when I do they’re a godsend.
