I tried to make an account and it's just way too suspicious to be legit.  Seems like a slick and devious scam and no doubt once they have access to enough wallets they will transfer it all out (BTC and BTG).  Domain tools (http://whois.domaintools.com/btgolds.org) show that it was registered 3 days ago (10-24) with only 1 year registration.  The languages are English, Chinese, Japanese, and Korean with no European languages so that would indicate that this is based in Asia.

Also, a site that was created after the fork is telling you to move your BTC to a wallet to claim your gold.  no.....  No doubt they will clean up with this.  If they had used SSL and added a login link I would have left this at a question mark instead of changing it to an exclamation point.
