I am able to login, to read messages, to create new discussions but not able to reply on the existing posts. When I press on "Reply" - simply nothing happens 
Additional minor bug - I am unable to see my points (right after Log Out).
iPad Air, iOS 8.1.2 (latest at the moment). Web browser - standard Safari. JavaScript - enabled, Popup block - disabled.
I suspect iOS update...
