When you add new files to share, the no. of files being shared will increase. This no. can be seen at bottom of window. See sample image below. Once you've added the files/folders to share, they will find it in their searches. Go to your Library window, click on the folder you're sharing & look to the far right columns. You will see Uploads & Hits. Hits represents no. of people who found those files in their searches. Uploads represents no. of uploads or attempted uploads.

Do you see a brick wall in front of the blue world icon at the bottom of LW's interface? Sample image: http://www.gnutellaforums.com/attach...1&d=1162908502
If not then you're right to go & sharing won't be a problem.
