So I hunted and saw some discussion in this thread but it died out a couple years ago. My question to the MT crowd:
What's in your email signature? Do you have multiple signatures? Do you put credentials/certifications in your signature or not?
I've got 4 signatures in my email client that I use depending on the situation (quickie mail, internal formal, external formal, and generic departmental). They range from "Thank you, Jared" to "full name, MBA; full contact info (internal phone, cell, pager, address, etc)". I'll probably get tired of having MBA after my name after the newness wears off (graduated in June). Back when I was a technician, I had all of my IT certs in my sig, but I removed them upon becoming manager (I have them all hanging up in my office now).
