Chatting
 

Some people were downloading off me and they had smiley faces in their chat column, I was wondering how do I actually chat to them?.

Right-click on them & you'll see a chat option show. But you also need chat enabled to be able to chat. Tools>Options>Chat

But keep in mind, lots of people leave LW running overnight or whilst they're at school/work, or hidden in the background whilst they're doing other things on the computer.

good point whoever u r. let me know if u get any replies!;)
