how do I do it ? Can anyone help please, I have got plenty music to share !

If you mean how do you make your music files available to other Gnutella Network users, click on Tools>Options>Sharing and click the Add button. Input the full path details (in my case it's C:\Documents and Settings\My Documents\My Music) but you'll need to input your own details then click Apply to save the changes. Bear in mind that every file in your chosen folder will be available for sharing.
