Bit of a derailment, sorry about that:
If we make you take your MP3 trading to email, you're less likely to get caught. Do it in public and you're at greater risk, too.
But what Alatar would be doing would be perfectly legal for him (I don't know about Ireland, but in Germany, for example, (AFAIK) it's ok to give your friend a copy of a CD as a present) - so he's not at any risk, if he's talking about it in public.
I guess it's ok to say 'better safe than sorry', and refrain from talking about things that are illegal somewhere, even if they are legal for you?
(Although, how are we to know what's legal or not all over the world?)
Maybe we need some more info on how this works?
Say, the board is under the laws of the US - does that mean anything that's said here must correspond to the laws of the US?
Because, if so, that would be comparatively easy, as we'd "only" have to know the laws of the US.
