Re: Tax Technicians
"Ok, I get protecting "Engineer" and getting all stroppy about stupid titles using the word engineer (I for one get extremely narked off) "
Actually, "Engineer" - according to the OED - extends about as far as "Technician".
"4. With preceding modifying word: a person considered to have specialized knowledge or skills in a particular field, esp. one who attempts to influence or manipulate human affairs according to scientific or technical principles." (dates to 1720, referring to "spiritual engineers".)
" 5. An author or designer of something; a plotter, a schemer." ( dates to the 16th century with Middle English, with another quote from 1998.)
I think people worried about "protecting" words need to either take a chill pill or at least consult the OED first.
