i agree with both silk and thommi about the chat.
if i'm downloading from someones list and it's all good stuff, i'll send them a message letting them know they have an awesome list or whatever i dont always get a reply but sometimes a thankyou and thats it. Dont turn chat on if your not going to use it. In 2 years i have only had one conversation, i'm in Adelaide and i spoke to a guy in germany for over an hour while we downloaded from each other,thats how it should always be, hope to chat to you guys one day.
