I don't use zero,   but I think you have your target market wrong.

This forum is for bookkeepers and Accountants.

Those on this site who use xero already have access to direct support but more importantly are required to go through full training.   This training has to be completed when they set up as a partner, but also to be certified they have to undertake it every year.  Ive heard that the training is comprehensive.  Also that its is actually very time consuming, annoying and costly (lots of moans about it on another accounting forum). Annoying because as most of them have said, once they have done the initial training it's not rocket science.

Private users get 24/7 support from zero direct (or via their help files)and are already paying heavily for it in their monthly fee, but wouldnt come on here looking for help. (or would be shown the door if they did!)

On the link itself - when you first click on it it seems to purport, on the face of it,  that its an official xero video rather than produced by a third party.   Do you have their permission to use their logo in your own videos?   It is only when you click on a video that you realise you are through to a third party provider of information.  

Have to say the sound quality is absolutely dreadful.
