Happy to help. If you scroll to the bottom of the challenge you're doing (right below where you download the workflow), you'll see a REPLY button to the far right. Click on that. This way you're responding to the original weekly challenge and not someone else's response. Next, enter any text response in the Body section , click on the triangle with an ! to enter a spoiler image and/or text, drag you workflow file to the 'drop here or browse files to attach' section, use PREVIEW to view before sending, then when satisfied select POST. I use the windows Snipping tool to capture my workflow images. I've attached one to show you.
