If you would like to include a Youtube video in your post, it could not be simpler. All you need is the video code, which is found after the "v=". So let us say for example you would like to post the Youtube video of "Trouble FREE Bell Syphon - Automatic Siphon Aquaponics Flood & Drain Beds". You first need to grab the URL, which in this case is "https://www.youtube.com/watch?v=CXaruS5z_Xc". So you need to copy and paste the code after the "v=" which in this case is "CXaruS5z_Xc".
Next click on the "YouTube icon". . When you click on it code will appear in your post.
You next need to post your code between the code. [Y0UTUBE]CXaruS5z_Xc[/Y0UTUBE].
If done correctly, you will get the following in your post when posted.
