Checking this site out. Not much going on here, but I expect that to change as time goes on.
My initial thoughts, this feels like just one giant forum, and not a unique forum at that. I feel like I could achieve the same thing by going to one of those free forum hosting sites and setting something up along with Squarespace. It's not very welcoming as a social platform, especially when compared to other social sites that are so dynamic and unique.
But with that said, I really do hope you are able to make this site into something special. What kind of team do you have working on this? What is the goal of this site? Why did you set this up? It almost feels a little like a project for college, or even high school.
I'll be around to watch over this project, see where it goes, and how I can help here and there.
