GaulDong is the first dynamic web application I've ever created, and still running right now with tens of thousands of members, and it has evolved many times, both for the better or worse (currently for the worse, unfortunately).
GaulDong is made possible by the kind guys at Indoglobal. Thank you, guys! Indoglobal is an Indonesian webhosting provider, but they provide international webhosting too. They offer advanced services at a competitive price, I truly recommend you to look at their services if you need a web hosting. They have a free trial so you don't have to pay if you don't like the service.
