The information you need to enter here must be given to you by your ISP or your Usenet company.
Name box: Enter a descriptive name here. It can be anything.
Server URL box: Enter the URL of your Usenet server. It should look something like this: news.yourISP.com.
Username and Password boxes: Enter a user name and password if your ISP requires you to do so. Otherwise, make sure to leave them blank. If you fill them in when they are not required, you may not be able to logon to the server. Usenet servers often have a different username and password than those used to logon to your ISP, or retrieve your email. When in doubt, ask your ISP.
