Earlier, we noted that BarbieGirls, apparently by accident, re-ran their launch announcement press release previously dated July 7th. Likely it's this latest they meant to announce -- that they're up to 4 million users since its launch (they recently claimed 3 million users in 60 days in mid-July).

According to the release, BarbieGirls continues to grow at an average rate of 45,000 users per day. While that's certainly nothing to sneeze at, it does signify a bit of a slowdown in signups for the site -- the release itself quoted GigaOM's Wagner James Au:

"In the first 60 days of its existence, the new online virtual world Barbie Girls has signed up three million members, and they’re adding new ones at the rate of 50,000 a day,” said Wagner James Au, GigaOM. “This is staggering growth by any standard, but even more so because Mattel’s MMO is still in Beta.”

The go-live date is August 13th, and will be launched in English, French, Spanish, Italian, German and Portuguese, as previously reported in the initial announcement. Mattel also says it'll bolster safety features "later this summer" with the addition of parental controls that will require parental permission via e-mail for girls to register on BarbieGirls.com and access certain chat functionality. The beta already features the ability for users to lock their rooms to other characters, block and report offending users, and "robust" moderation.
