I see there is an insert flash function, but I'm not sure how to insert a youtube video or any flash video for that matter. Help would be appreciated.
IIRC flash was never enabled in the forum so it can't be used.Edit: What you can do is just upload an image then link it to the video instead or follow this:
1. Get the Youtube video link e.g. https://www.youtube.com/watch?v=Gc2en3nHxA4 (Remember this id Gc2en3nHxA4)
2. There are 4 a default thumbnail images to each video the, URL to these images will be like
Code:
https://img.youtube.com/vi//0.jpg
https://img.youtube.com/vi//1.jpg
https://img.youtube.com/vi//2.jpg
https://img.youtube.com/vi//3.jpg
3. Now to add or embed youtube video, add img tag and replace Youtube Video id
Code:
[img]https://img.youtube.com/vi/Gc2en3nHxA4/0.jpg[/img]
4. Now add URL tag and point URL to actual youtube video
Code:
[url=https://www.youtube.com/watch?v=Gc2en3nHxA4][img]https://img.youtube.com/vi/Gc2en3nHxA4/0.jpg[/img][/url]
5. Final result, Youtube video, click to play
https://img.youtube.com/vi/Gc2en3nHxA4/0.jpg
The only thing should be added, as for me: to do so, you need to be Jr. Member at least or Copper Member (just in case somebody new to this forum would be reading this).
