This is a great component for anyone who wants to offer classified ads services in their sites. It's very configurable with tons of options in the backend. I recommend subscribing to one of the available support services if you are serious about getting things done - they are fast and direct answering your questions. There are many optional addons, but the standard addons may be sufficient for many. I understand that they are continuing to create more addons, which could give your ad site lots of flexibilities.
Good job guys.
