For the game Cloudstone: http://armorgames.com/cloudstone-game/15364
If you click the "Visit the Forum"/"Contact Support" tabs on the right side of the game window it sends you to not entirely correct linkages. (I should have stated in the title that the ArmorGames links are not correct.)
Currently it sends you to forums.cloudstonegame.com which is incorrect, it should send you to forums.playsaurus.com
I have a feeling that the existing links are simply out-of-date as they are partially functional. The existing link does allow you to see the forum main page, but it does not allow you to log in from there without returning a 503 error. Clicking on anything from that page sends you to forums.playsaurus.com instead. As the game tells you when you first log in, the proper link should be forums.playsaurus.com
