Social Groups available at Mustangboards.com
Not sure how many people have seen this.
You can start your own social group now.
Go to USER CP, then on the left pane there is a link "Social Groups"
once in there you can start your own group for whatever, make it private or invite only. We already have a red mustang group and i started a photography group.
It is pretty easy to overlook and one of the new features since the admins upgraded the site.
