Email Etiquette
If you would like me to respond to e-mail, you need to have a little bit of etiquette. The most obvious is to indicate who you are. I do not memorize your email address, so I cannot recognize thedudeman99@whatever.com as you. Pretend this like a semi formal letter. All you have to do in mention your name.
Some professionalism is appropriate. I am not your buddy who you send email jokes too. I am your college chemistry professor. No need to send me some cool chemistry joke you got from a friend. Trust me, I saw it long before you did.
