Legal issues were mentioned before, we must respect them or get our behinds sued off in case someone court-happy enters.
I propose a disclaimer:
I am above 18 years of age. If I am not and enter nontheless, b77 will not be held responsible for any offense or damage to the soul I might be taking through foul language, explicit thesauri and holby's sig pics, and boy, there's a lot of damage to be taken. In any case, if I enter, I will be treated as if I were above 18 years of age, which is something quite unusual on other boards. And if you misbehave, you'll get punched like a bag until you wish you'd never hit the "enter" button, even though you may be already in retirement and are an elder statesman who once played a leading role.
I wish I were above 18 years of age.
