Hi, I'm a first time user of Limewire and until I'm up to speed with how it all works, I'm really keen to ensure I haven't given everyone open access to my entire hard drive/computer (iMAC). Appreciate the whole idea of this product is to 'share' so I'm not trying to 'not contribute', but until I find out how to set-up up which of my files I make accessible, am nervous about giving someone open slather access to the works. Can any well tell me how I determine what on my computer, is accessible/available for sharing? I can find where to modify/check this. Thanks very much. Dave
