For some odd reason, if you have Chat enabled, it is much easier for people to browse you. You are refering to (a) Browse aren't you & not just (b) sharing your files so they can find them is a search?

(a) See How to use Chat & Direct Connect, etc.

(b) Go to your LW Library window. Select any folders you have set up to share. If they are listed in black then they are being shared. To the far right columns under uploads & hits you can see if people have found them in searches or uploaded any files.
