Also, since you couldn't post messages, you did not get involved in the process by posting messages and responding to other people. There are some misconceptions I wish to clear. Newsgroups are not a part of Netscape. Internet is a network of computers. It is best to think of internet as a community of people with computers.
People use the internet to communicate.
There are several processes that are used for communication. Electronic mail is used to send messages from one user to one or more specific users. FTP or file transfer protocol is used to transfer files from one computer to another. Newsgroups are used to post messages and read other people's messages. Think of newsgroups as a central bulletin board for messages and notes.
