In British English we usually use the name "scissors" rather than "pair of scissors"
In American English "scissors" is far more common than "pair of scissors" as well, though both are used.
Don't hold your breath! They may not get round to fixing it for months. They are volunteers and hardly any students are paying for the course (how many times have you seen "PLUS" after someone's name?) so we can't really complain.
They shouldn't be volunteers. They should be paid. Isn't that one reason we're putting up all these ads?
