Yes, finally CJ Entus has opened up an English version of it's Korean official website.
http://www.cjentus.com/english/index.html
There are a few very endearing mistakes (grammar/sentence construction and a photo for Effort's profile etc.) on the site right now - including this one;
It's looking like a nice, clean lay out and hopefully they will add more content to the shopping mall and other sections in the future. The community board is looking mightly lonely so it might be a good time to start leaving supportive messages to encourage them to expand the site.
The status of the other proteams sites are as follows:
Hwaseung OZ: Only Korean (Can post on boards without Korean Social number.)
eSTRO: Supports some English (Can sign up without Korean Social number and post to boards/galleries etc!)
Hite Sparkyz: Only Korean (cannot sign up without Korean Social number.)
KTF MagicNs: Only Korean (cannot sign up without Korean Social number.)
Air Force Ace: Only Korean (cannot sign up without Korean Social number/Ipin.)
STX Soul: Only Korean (cannot sign up without Korean Social number.)
