There is no central server! Doh! What's more this is a forum which caters for multiple p2p apps. You're downlding from people like yourself, your next door neighbour or somebody over the other side of the planet. What these people share is up to them. But there's nothing illegal about sharing so long as it doesn't include copyright or warez. For legal reasons we are unable to discuss about warez issues. And if you had have seen the forum rules, there's 2 copies posted in every single section of the forum, then you'd be aware you cannot post asking about warez info.

By the way I hope you didn't get your LW from a scam site. THIS is the real LW site: http://www.limewire.com/english/content/download.shtml Notice there's no advertising of music or programs or games or movies, etc.!!!

In answer to your 1st question, I wouldn't bother with it. Those people who do that with passwords are AH's! Try another.
