....THIS IS A PARTIAL REPLY TO YOUR QUESTION, AND ALSO A QUESTION AT THE SAME TIME...
EVERY TIME I OPEN LIMEWIRE, THE SYSTEM TELLS ME THAT I AM UNDER AN "ULTRAPEER", SO IT WILL BE DIFFICULT FOR THE OTHERS TO MAKE RESEARCHES INSIDE MY FILES. MOREOVER, I CAN NOTICE THAT WHEN SOMEONE IS CONNECTED TO MY LIMEWIRE FILES FROM OUTSIDE, THE CONNECTION OFTEN GETS SHUT DOWN.
JUST LIKE YOU, I THINK THAT IF I CAN DOWNLOAD SOMETHING FROM THE OTHERS, THE OTHERS MUST BE ABLE TO DONWLOAD SOMETHING FROM MY FILES.....SO, WHEN I STARTED TO USE LIMEWIRE I DISABLED THE FIREWALL, BUT NOTHING CHANGED.....AND I AM USING A FAST DSL LINE.
ACTUALLY, I CAN'T SAY NOW IF OTHER PEOPLE ARE ABLE TO GET FILES FROM ME, BUT ANYWAY I DON'T KNOW WHAT TO DO MORE.......

BYE TO EVERYBODY
