Changes

* '''Giving thanks.''' Putting some type of thank you in your email signature reduces the sentiment to crass insincerity. If you want to thank someone in an email, thank them specifically, otherwise leave it off. Finishing an email off with “cheers” or similar informal greeting can offend some recipients.

* '''Mobile Signatures.''' The default signature of mobile devices that say “sent from my iPhone” or similar provides marketing for the manufacturer but make you look stupid. Either you think using that device makes you cool (it doesn’t) or you’re too dumb to know how to change the message. Instead, change the signature to “sent from a mobile phone, please excuse brevity, spelling and grammar”.
