Email etiquette

If you type in all caps, you are screaming at me.

If you don't take the time to punctuate with any semblance of effort, you are saying you have more important things to do than communicate with me.

If I ask two questions and you only answer one, I know you didn't take time to read my email, and probably should be skeptical of the one answer you did give.

If I copy someone on an email to you but you only reply back to me, it looks like you're hiding something (or, again, aren't paying attention).

Email's great and email's fast, but email also says a lot about how you value me.
