Ever set up a 50MB download and gone to sleep, only to find you only got the first file before your news server had some silly error and your download stopped? With this feature (which also works with any auto-reconnect util) you can depend on NewsShark to do whatever it takes to keep that download going (even if you are asleep). :)
Why bother downloading the whole post again? NewsShark caches parts to disk (until they are decoded), and if a download interruption occurs, you will only lose how much ever you had of the current part.
