I started to compose a new thread, and as usual got completely tied up with the picture posting process. I wanted to delete the unposted thread and start over, but no matter what I do--deleting the text and pictures, closing the NAWCC tab, etc--when I come back and click the "post new thread" button, my old, unfinished post appears. How can I get rid of it? And, I see that I have a typo in the title of this thread, but the edit button doesn't allow me to change that. Why not?
