Unison - the best Usenet browser for Mac - gets even better
If you're on newsgroups to actually read news, Unison makes it simple. The highly-organized thread view lets you read all the messages in a group in one continuous flow, and makes it clear and easy to follow the replies. If you're a bit more old-school, or you just know exactly what you're looking for, you can also browse through the messages one-by-one. Searching for new groups and adding them to your favorites is also a cinch.
Unison has you covered when it comes to files, too. The aforementioned file search is handy, and you can batch-download a group of files once you find what you're looking for. Media files, like images and music, show up inline in the message view. That makes it easy to take advantage of Unison's ability to stream music right off the server before you download. And, once your files are done, Unison can automatically unRAR, unPAR, or otherwise unarchive them for you. Don't miss this app if you're a Usenet junkie.
