No no. My post was a general discussion message for everyone, not just for you. So, whoever reads my review of the beta site, who has NOT signed up on the beta site yet, should create a username on the beta site in order to read my post. If you check the current JCJP forum page, I invited everyone to check out my post on the beta site. Sorry for the confusion.
I wish I could delete comments after posting them. Just ignore my last post. And to answer your question, yes, I tried logging into the beta site with my current JCJP username ... I created the account October 12, 2013, so my username did not exist prior to the beta site launch.
