This is a small operation and video content takes up a lot of space, so we can’t and won’t host video content directly here. You can still post videos, but you need to upload them somewhere else first. I recommend YouTube and then posting a link here, so that people without Facebook accounts can see the video.
As for PDFs, it’s the same issue, but I’m also thinking about adding a “museum” part to https://5pin-talk.ca, so if you have PDFs that you’d like to post, send me a PM and we’ll figure out how best to do that. For example, I have one package of content in my inbox to post, thanks to @brad_tytgat.
