OUI, the Offline Usenet Interface

OUI supports SLIP, PPP, and any valid TCP/IP Winsock-compliant connection. That means you can use your favorite dialer. Once online, OUI will download the headers in the Newsgroups you've subscribed to and then disconnect automatically (if your dialer supports the disconnect command OUI sends). OUI works with Microsoft's dial up network (DUN) as well as other dialers. OUI also works with a LAN connection or a high speed connection such as a cable modem.

You may then take your time to review the headers and mark which messages you would like to see. One more simple click and OUI will go online, download the messages you marked, and then come offline. You may then read and respond to the messages at your leisure.
