Our guild is kind of similar to how you are describing yours. Except normally by the time we get worse for wear they had long gone to bed.
My thread was more about the point of, do you think it is ok letting kids and adults mix online especially in today's culture? If you had kids that kind of thing.
While there are dangers on the internet as long as you teach your kids correctly they cannot get hurt in any way like they could if you let them go play outside.
I think it's a good thing that different ages mingle on the net when it works out. I'm friends with a guy over in the US whose nearly 20years my senior and I've known him for about 10 years. He has a wife and kids and I speak to them all regularly aswell as play CoD2/4 and SC2.
