After spending the past few months learning Drupal, and trying to get a decent classified ad site up and running on a hosting plan that doesn't offer old versions of Drupal, I decided to give Joomla a try, my first extension was AdsManager. Wow! I installed Joomla, installed AdsManager, and would have been up and running in a day, but it took me two after deleting the Main Menu (problem in Joomla, not AdsManager). So a quick re-install, and the most time consuming part was re-entering the categories. Don't know how they plan to make it better, but I might come back with some advice later!
Joomla+AdsManager=Classified Ad Website to rival Craigslist (almost).
