Overall I thought this was video was decent.
Shorter is better, you could do a supplemental video with extra information to cover the points you left out from the 17-minute version if you thought it was necessary. The length wasn’t too burdensome in my opinion.
That wouldn’t hurt.
This would be important for a lot of people.
The video says, “Occasionally you can put a link to a picture, we really don’t like that because we don’t have control over the photo…”. That’s the first I heard that, I thought the reason for allowing linking to images was to prevent guests from taking up server space without supporting the forum. If your concern is links becoming dead in the future then I’d considering banning links like ICE suggested.
Lastly, I noticed on the YouTube preview image you show a logo with a building but on the YouTube channel you have the hammerhead logo (which also shows in the top-left of the YouTube video preview,) I’d coordinate the use of the logos.
