I write here about email etiquette, but I recently received an encouraging email. If we got emails like these all the time, we wouldn’t need to discuss email etiquette.
The nicest part (for reading anyway) said:
As a graduate instructor at the University of xx, I just wanted to send a quick note of thanks for your website. It has provided me with extensive information in teaching my courses at Uxx (first-year composition and technical writing), as well as in developing my own professional knowledge base and skill set (through CFPs, helpful hints, etc.).
It is always good to know that what is being done is useful to someone. I especially appreciate it when the someone is a teacher, since that was part of my goal with starting this website.
