Adding a signature to your e-mail -- especially when you're working from a smartphone -- can be either a badge of honor, or an excuse. (The joke goes that you can get away with typo after typo so long as your signature says "Sent from my iPhone.)
Adding a signature in your Android smartphone's gmail account is easy.
- Fire up ye olde gmail application.
- Press the menu button.
- Choose "More."
- Choose "Settings."
- Tap "Signature."
- Type the snarky statement of your choice.
- Click OK.
- Send e-mail.
Signatures don't have to (and probably shouldn't be) full of snark, but they can be handy to let the recipient know that you're working from a phone, and so the response might not be as long as it would be if you were working from a desktop. Typos are still on you, however.
