Hey, nice video.
I have one question: It's about WordPress- what version of it are you using now? The reason I asked this question is that my WordPress seems a lot different from the previous one I am used to as the one that you were using in this video.
Linking works in quite a similar way in a new WordPress version. You can search on YouTube "How to post a link on WordPress 2019" and you'll find something that's created this year and most likely with the most updated WordPress.
Thanks for comments on the video, It was a mess but so many people were inquiring on how to do so, so I did it holding my phone the whole time LOL as for your question on wordpress Just the updated version 5.1.1
