I’m not sure how many operators know this but after making a post on the bulletin board, we all think of something else we should have added to it. Rather than making a new post, just edit the post you want to add something to and then repost it. The edit button is at the top right hand of your posting, and left of your picture. I’ve had to do it several times after reading my post and it does not convey what I wanted it to. You can also delete your post also if so desired.
