wp_list_authors() gives a list of author pages permalinks (site.com/author/john, site.com/author/jenny, etc). I want the same links using
get_userdata() functions instead. I need these functions because I display authors in a very customized way. However I don't know how to get proper author page slugs with those functions.
(for example, one author has an email address as her Username, and the
wp_list_authors()-generated link for her author page has dashes in place of the "@" and the ".". This is to say that the author page slug is not necessarily the same thing as the username)
