Not sure why you would have a problem. Nothing's been changed with the system and lots of people add listings regularly. What browser and version are you using, also are you using HTTP 1.0 or 1.1 (the newest versions of IE or NS allow you to change this setting... use HTTP 1.1). The user's rides form is a large one, perhaps the browser version you're using has a bug with large POST submissions or with handling gzip compression.
