I did my redirect by pointing my camp2019.videos subdomain to a Youtube video. Very easy.
I can see this as being a great way to share instead of using a bit.ly link. For example, if you are doing a presentation and you have a PowerPoint, video or handout – you could send them to a subdomain which would point to the file.
For example, I uploaded a PDF to my site. I would like to share it with a group. Rather than give them this link: https://learn4growth.com/2019screens/Surface%20Pro%20%E2%80%93%20Uses%20for%20Teaching%20and%20Learning%202018.pdf
I am able to give them camp2019.handout.learn4growth.com and it redirects to the PDF file.
