There's no such thing as a stupid question. You came to the right place. In LimeWire, if you click on the "Monitor" tab, there are two main areas. The "Incoming Searches" area at the top, and the "Uploads" section at the bottom of the page. Under the uploads area, there is a list that will tell you if anyone is uploading from you. It will also tell you the name of the file, the host address, the size, status, progress, speed, etc. If you have multiple uploads taking place, there will be several entries on the list.

Hope this helped. Enjoy LimeWire! :-)
