During the Unite conference, Unity Technologies announced that 6,500 people have signed up and joined the Unity community in the past 48 hours.
"We announced in the keynote that we had 13,000 registered members now, and that's taken us five years," said Unity product evangelist Tom Higgins.
"Within 48 hours we've added another 6,500 to that number."
Although many of these will have been merely to download the Unity package, it's likely that a good percentage of these will stick around - further enriching the community, which Unity uses as one of its selling points.
Develop has also heard that at least one high-profile customer of Unity has praised the move, saying that it will give them a wider base of people to hire from.
