Where did the postopia website go?

I used to play on postopia; it had games like waffle boy's mountain adventure. I looked for this site recently, but apparently they redesigned and made it all flintstone based! The flintstone website only has four games, which is strange because the old website had a lot! I have been wanting to play waffle boy (nostalgia) but I cannot find it anywhere. Does anyone know what made the post people decide to switch from postopia to all flintstones? Also, is there anywhere that I can play the old games?
