Hi guys, I didn't really know where to put this, if it is in wrong section please point me in right direction.
My question is really about http://d3db.com - Does anyone here visit it alot and if so, I wanted to ask - you know how they have the achievement system incorporated and flashes up if you perform certain stuff whilst logged in. Anyone knows how that is done or what is used to get those nice pop ups and icons and such. Or at least point me in right direction. Basically I am looking for a way to implement similar achievement system for a website and would like to learn on how to do that.
