Finally, I have put together a small video showing how the concept might work. It’s a sketch video, just to illustrate the how PO Box might work. I have also included some graphics (which may take a wee bit longer than normal to download, be patient!) to give you mroe detail on how it might work. I would really appreciate feedback on the concept. If you think there is anything missing from it, something that might not work, or perhaps you really like it, I’d love to hear from you! It would be great if you could also show it to others or pass on the blog link to someone you might think will be able to provide feedback.
