Mozilla Seamonkey can be used offline but lacks the more powerful features normally found in a stand-alone newsreader. If you do decide to use it, please configure it not to post HTML or attach Vcards to newsgroups postings. In case you’re interested in finding a better newsreader, here are some suggestions:
A good offline newsreader for the Mac is MacSOUP. It’s shareware: you can try it for free, but if you decide to keep it, you should pay for it.
Windows: Forté Agent
Agent is one of the best offline newsreaders available for Windows. (Free Agent has been discontinued.)
For assistance in using Agent, subscribe to the newsgroup alt.usenet.offline-reader.forte-agent.
