Searching for a how-to on changing author slug, I found two methods:
user_nicenamefield in the MySQL database of your WordPress site to whatever you want the slug to be.
The (2) is out of question because I want the slug to be something custom, but not the nickname/nicename.
As for (1) I wanted to know if this is okay -- to change the value of
user_nicename field in the database for the user?
