Beanstalk has been in private beta for a little over a week now. So far, the response has been exceptional and the feedback has been very useful. We are going to issue a second round of Beanstalk invites next week in order to gather more feedback. We are limited to only 30 more accounts for this stage.
If you are interested, please sign up on the beta site to request an invitation. You should expect to receive an email by the end of the week or early next week. Request an invite.
