I have installed Xnews. That is my 2nd (tied with defunct Newsgrabber) favorite binary reader. But the problem with Xnews is that the learning curve is steep. I am "slowly" learning how to use it. The manual is on the skimpy side. This newsgroup: news.software.readers will help all newcomers understand Xnews. I like Xnews because it doesn't "waste" any of my real estate screen, but News Rover does. News Rover is good, but they need to improve on the truncating the windows. It's been awhile since I've used it, so maybe things have improved by now. The interface is on the klunky side, but it has good features in there.
Xnews and GrabIt are freeware.
BTW, anybody know what happened to the programmer of Newsgrabber? Why did he abandon it?
