Fixed - Suggestion to improve audio quality of tutors' introductory videos

hi i just went through the section 'find a tutor' and i have noticed the differing audio quality of video messages. Some tutors were very clear and loud whereas others were not. Kindly ensure the audio quality of video messages first as it will make a good impression. 

This is some good advice. I will make sure this gets included when we write the FAQs for teachers.
