skritter issues

I love skritter but cannot access it from the chinesepod site without a vpn. If I go to skitter .com - it says it has been blocked because it is hosted on goggle app engine, so periodically blocked. It gives a mirror site www.skritter.cn but premium users do not access rights to it.  Could chinesepod provide the chinese mirror link for poddies in china.

Secondly, I have found it good - but I wondered why the basic vocabulary is not loaded on it - it is often the supplementary vocabulary - which as a newbie is not my main focus.  Is there a way we can load the vocabulary we need from the lesson?  

Thank you
