It's been a few years since I watched CL closely, but I simply subscribed to the RSS feeds which sent me notifications to my email. I expect you all have posted to Craigs List then waited patiently for your post to appear. What I learned was that CL must "batch" postings on some sort of timetable. However, the RSS feeds did not seem to be bound by that timetable...so quite often, I would receive and RSS feed email before the posting actually appeared on CL.... Good luck and good hunting.
