that's just the reverse of the weird way things work in Australia- it's illegal to sell cigarettes to minors, but it's not a crime for a minor to smoke.
you're not supposed to post (well, discouraged from posting) homework questions (ie: what's the answer to 2+3?) But there is no rule against answering homework questions. (ie: 5!)
I agree though- when it's a good question, go a head and help.
Spoonfeeding/copypasting just isn't helpful- if people actually learn why the solution works, then they can tweak it for the unique situation they have. Copy and pasting someone else's grub file usually won't work, for example.
sorry- you can take my soapbox away from me now.
