If you like to watch, your voyeuristic streak can be satisfied from the search monitor screen.
The search monitor displays every search request that passes through your machine. If you see something you like, double-click on it to jump on that search's bandwagon.
Keep in mind that since Gnutella is used for much more than just mp3 files, there's a good chance that the search monitor will be chock-full of dirty words. Because one thing is for sure - where there's a good search engine, there's people looking for porno. So, if you're sensitive to such things, it's best to leave the monitor disabled.
That's really all there is to it. Sounds easy, right? Gnutella strips the concept of file-sharing down to the bare essentials and does it all without central servers, not to mention useless chat rooms. Since no one person controls the Gnutella network or the software that powers it, it's likely that Gnutella-related software will be around for quite some time.
