Currently, when I grade a student essay in Speedgrader and I enter a comment about something they have written, that comment is flagged out to the right of the student work with the title "Rob." That is of course my first name. Wouldn't it be a bit more professional to have at the very least a LAST NAME in that field rather than a First Name. Students do not know me by "Rob." They know me as "Mr. Hensley."
In my case "Hensley" would be sufficient, however, if an honorific could be applied, that would be nice too. It raises the professional bar a bit.
