@Serioussweetie - In the upper right of your post (by the number) you can click to edit your post within 15 minutes. After that you cannot edit your post. You are not able to delete a post at all. However, if you go in within 15 minutes you can delete the contents…sometimes you’ll see people’s posts as “deleted” because they replaced the contents with the word “deleted” within the 15 minute window.
