Hello again (my 2nd post) and a comment that this is a terrific site for professional info. However, sometimes a tad too professional because everyone seems to talk in acronyms (illegal in medicine and nursing circles ya know).
I see robots.txt discussed in posts but I don't know what this is. I assume meta robot tag is not robot.txt.
I really hope this isn't too dumb a question from a learner/student etc.
