HUGE reduction of file storage (iNodes) by adding an external IMAGE HOST service
A very normal limit of major web host companies, like SiteGround offer a maximum of 450.000 iNodes (files), even in the GoGeek plan. This is absolutely not enough when your site grows to a medium size and each visitor posts 1 or 2 images. Why forcing to spend lots of money, since there are external (free) image hosts. Then you don't let users pay the hosting of the images, but enable them to store their pictures externally. So why not adding an external image host integration.
FREE & For (big) auction and forum sites:
They offer professional and practical nice plugins and they have a smart marketing plan, why they can offer it for free. Maybe you can contact them to combine their service with yours. Hopefully they will add the name DJ Classifieds to their site then!
