For instance, if author Smith wants to publish this site, he can use smith-author.weebly.com (a fictitious one; just for the purpose of an example) if it is available otherwise he may need to modify it a little to get an available one.
This is exactly how modern technology will enable you to create a remarkable website without starting from scratch. You also have the option to purchase a main domain so that Weebly or Wix wouldn’t appear in the URL.
