Using Ruby to Post to Craigslist

I need a procedure written in Ruby that will post an advertisement to craigslist. This is the link that I need the ad posted to [login to view URL] I need the procedure to return to me a link that will take me directly to the 'Preview ad page'. For example here is a link to the edit ad page [login to view URL] But I still need to hit the continue button before I can proceed to the page I want to view. I want to remove this annoying extra step. ## Deliverables This should be a very simple ruby script. You will probably need to use the http or https libraries. If you need to parse html responses please use the hpricot library.
