You sure learn quickly! (interesting about the 100).

Re 2--you can download from any speed--some people only download from higher speeds, which means the modem users often get overlooked. I've had some great results from modem users.

re 3, "Shared" is the default name of the folder LW automatically uses to share the files within it. Other programs also have folders called "Shared" (if you open your hard drive on OSX and look in the "Users Folder" you'll see another folder called "Shared" It's the one all the users at your keyboard can access and has nothing to do with LW.

You can share any folder you want: when in the "Library" Pane of LW, the file menu will change so you can add or remove other folders. ONLY the folders listed in your Library are shared by LW, so you can always see what you have allowed other LW users to see.

Sometimes it's just easier to share one of your iTunes folders: that way both programs can access the same files.

Cheers--and ask away! We all learn that way.
