This is how you comment on other things like videos and blogs. So, first you watch the video then where there’s comments there should be a link that says “comment” or something like that. Say things like “I love your video, but how do you do that” or something like that. Then you wait or do something while your comment is being looked at by the creator. Then they say something back. It’s kind of like texting, but a whole lot better. Trust me!
