Yeah, I think you need more information on what it really is. We can't really have much of an opinion either way without knowing more than the words they chose for their name.
My speculation (and this is purely speculation lacking any real info) I wonder if it is a reaction to the way many congregations treat their youth? I disagree with the idea of having a church that divides the body of Christ and would seek to marginalize a particular group of brothers and sisters based on something such as age (in this case seemingly eliminating anyone over a certain arbitrary age limit), as the name of this one seems to suggest they might be doing. However, if you really think about it, this is what many of our mainstream congregations do to our youth now. Instead of the youth program supplementing their total church involvement, they are marginalized at best and sent off to their own little group, therefor eliminating them from the main body of the church, it's functions, and of any "ownership" in it's direction. Then we wonder why we lose about 90% of them as soon as they graduate from high school (with the few that do return one day coming back mainly for selfish reasons such as needing help raising their own kids now).
I don't think I like the idea of an entire church just for the youth, but fear this may be a reaction to the way our churches in the US and other 1st world countries have treated our youth for far too long.
