If you log into WW via desktop, there is a dropdown on the top right where you can either flag a post, or "edit" it (if it's your own). However, although you can technically edit it, when you finish it refuses to post. Nothing happens when you click the button to save/post the edits you made. I just posted a really long one, and it's infuriating because it didn't include any of the line breaks I added between paragraphs so now it's a NIGHTMARE of a novel to read and I cannot fix it. Oy!
