What should a proper email signature look like for graduate students?
I'm not in academia, but my email signature looks like this:


  


If someone wants to know my name, it's sent in email headers and shows up at the top of the messages. If someone wants to know where I work, they can look at the part of my email after the @ sign.

And of course, if I'm contacting someone for the first time, I'll tell them who I am and why I'm contacting them in the body of the message, so there's no need to repeat it at the end of the message.

Here's an article similar to the one that convinced me to stop doing this. Basically, by including a signature, you make it harder to read an email. This is normally just annoying, but it becomes extremely frustrating in long email chains or mailing lists, since no one bothers removing signature when they quote people. So, save everyone the trouble and don't send it in the first place.
