Do I have to use WordPress?

Do I have to use WordPress?

Absolutely not.  Your webspace is yours to promote your business, and you can opt to build your own site, have someone else build a site for you, or use a content-management platform to make things easier.  WordPress just happens to be a global standard, with a vast array of plugins and addons, as well as themes and developers, and these all serve to make it the natural choice for most.  The AuthorPackages website itself is a WordPress build.
