Click on the "youtube" button right above the reply box, then insert the video address in between the [youtube ] and the [/youtube ].
So, your last vid post would look like [youtube ]https://youtu.be/OrljWGIHB7c[/youtube ] when you finish typing it out, but will appear in the post like this...
HOWEVER....it's best to not use the "Share" address under the vids...it's better to use the full address at the top of the page, in this case it's "https://www.youtube.com/watch?v=OrljWGIHB7c&feature=youtu.be". Also, in this case, you need to remove/delete the last part of the addy...the "&feature=youtu.be". If the addy includes all of that, it won't work here. Sometimes the full addy works fine, other times the addy needs to be edited like this. Don't know why that is.... :headscratch:
