If I can teach Son of Robert how to post an article I can teach you how to create a GIF. Couldn't be any easier with the GIF creator on this board.
There are 3 icons of 3 vertical dots at the top of each post when you open up to post. See all the icons up there? Click on the one about the middle of the page. You'll see a smiley face (those are the emojis you can use in posts) and then you'll see "GIF". Click on it. A box that says "search" will pop up with some GIFS. Write what you want to do with your GIF. For example, "how to teach someone". Click on the one you like and it will appear in your post. Got it? Let me know if you have any questions.
