iDXCluster

From Black Cat Systems:

iDXCluster is an easy to use DX Cluster program geared towards SW listeners, DXers, utility monitors, and others. It doesn't require a packet radio link, telnet, or any complicated software or setup, only an internet connection is requried.

A DX Cluster is a way for DXers to share tips on what stations they are currently hearing. Stale DX news is useless, so a DX Cluster allows people to share their loggings within seconds.

Just download the program, enter in your Name and location, and that's it. Loggings from other listeners will be displayed on the cluster screen in real-time. You can submit your own loggings as well of course. You can also filter the types of loggings you want to see, so you don't have to see stations that you have no interest in.
