The Fark “scratchpad” is a thread created to allow the user to test a post without everyone seeing those embarassing mistakes. If you’ve ever found yourself saying something like, “hey why didn’t that work?” or “what’s wrong with my image-size?!” this is the place to test settings without exposing your neophytic ignorance to the world at large. It’s a great place to see if your new image-host is working or to test a new format for posting photos or even to see if the file you want to post is too big. No one can see your posts except you and the modmins.
Use it!
