Why is this called the "main" website?

Because it is the focal point for a series of websites by the same author and webmaster.

All of the Internet activities by this author and webmaster ultimately link to this website, and this website in turn links to all of his other Internet activities.

Introduction

Don't expect these websites to replace your textbooks in the relevant fields. That is not why they were written.

Do expect them to include practical issues that were omitted from those textbooks.

Do expect the articles to supplement the articles with selected, Jewish-oriented material.
