Hi as a premiun member you can set up notifications which emails as soon as a new cache is listed within the guidlines you request EG. 80km from home co-ords, new listing only, trad, size or how ever you wish.
This email tells direction and distance and provides link to cache page for quick access to info.
If you are after FTF this is a great way to get ahead as the email usally comes a few minutes before it is showen on wed site.
