Hi
I have missed this great idea for Joomla banners and I think this could be improved and work with other Joomla components that you have started to to do now like integrate with EasySocial, (EasyBlog) etc
Others could be Flexbanner
extensions.joomla.org/extensions/extensi...anagement/flexbanner
and also Ijoomla AdAgency that is lacking this good feature of auction for selling banners.
Hope you push improve a little and post that update on Joomla JED - Joomla Extension Directory so more people can see this good addon you done and that it wlll be improved when more people discover and start using it!
Best wish of luck and I will come back to use this when I have a case ready. Maybe it could be good to have a system that work together with Google ads so when you not have an ad your self in that banner zone/postion then a Google ad will be shown instead. Like have a priority rule ad system where priority to show your own bannes first and second Google ads in that position..
