Some of the ads are user generated, some I “scrape” from other places on the web. Working on an aggressive marketing campaign as we speak. Everything is done via SAEF. Took me a while to get it to work like I wanted, but was well worth it. Even when an admin posts a listing, they do it via SAEF.
I was in the process of a homepage redesign as you posted cause several people told me the front page was confusing. Currently working on an About page, FAQ, etc. Initially I just wanted to get the core functionality working and now I will add improvements a little at time. If you get a chance, let me know what you think of the new homepage.
