Wow, what nice spammers you meet: give you real addresses. Mine all use fake sending addresses, so would never receive any challenge I sent. In fact, that is why I always thought some sort of challenge system would be effective - it would remove 99% of the spam that comes my way, which I, ignorantly, assumed was a representative sample. -- richard -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
