The Internet has developed so rapidly, because it has found great support from people at universities. Because of this, somewhat similar to the great number of UNIX tools, there is lots of software available completely or almost for free. Newer software systems like OS/2 Warp come with full versions of Email, WWW, and other 'information highway' software. A search on one of the large software servers should help you to find the software you need for almost any operating system.
There is lots of software for setting up own Web home pages and for editing text and storing it in HTML format.
