Last time I looked on youtube there was 3 videos explaining about unlockit.co.nz and what the website/service was all about. Now there are a lot more.
I have added them into a playlist so people can view them. If you have any videos you would like to make please get in touch with me and I can add them in as well.
All these videos describe in different manners in how the website works and how to use it. They also describe older versions of the website as well and they may not all be up to date in the information given.
If you have any trouble using my website please get in touch with me.
