I am brand new to LimeWire but had a very bad security experience with KaZaa and because of this I am afraid of sharing files. Can anyone advise me of how to protect my privacy while still sharing my music files? Previously someone had been uploading pictures of children and since my system is very simple (56k) and seldom used I didn't realize this was possible.

You imply that there is more than one user (i.e. yourself) on your machine.

If that is the case, than you must configure Administrator status for yourself and impose restrictions on any other users.

Connection 'speed' has nothing to do with it...

More info from you would help...
