It's fake! There isn't any announce on tracker about the open sign-up. And if you read comments on that thread you can see that no confirmation for the open sign up exist.

HDChina has a big problem when merge two databases of HDWinG and OpenMV, some of the user will have two accounts on HDChina.
They have to choose which account will be keep otherwise both of their account will be disabled. I think invite system will be closed untill this problem is solved completely. And of course won't any open sign up.
