How would people here was an adult board conducted? Do you want us to get ages of people, or control it some other way? Now note, even though it is an adult board, it will not allow for certain materials we will go over more in depth.
I mostly saw it as a place to take conversations which start going into areas that might upset passing soccer moms, not like a 24x7 extreme porn dump. EG, depending on how far someone wants to stretch child endangerment/corruption of a minor issues, the drinking thread might be better on an adult board.
As the current membership stands, I'd trust the staff to make the call for who qualifies; this could be revisited if the site's popularity booms and there are more strangers than familiar names. There's really not an easy way to ensure you have everyone's real age.
And yeah, take care of that cold.
