So navigate to the megathread that's currently up there, click on the three dots at the bottom right of the post that says "more" and a document will appear. Click the document, which will give you the text only version of the post. Copy the text, including the links and emotes, delete the information from the previous post (except for the links) and then create your post above the links. Add your post in the comm you wish to create it in and title it "something, something" megathread or a clever title of some sort. After you do that a mod will sticky the post then rip your notifications.
