Author Profile URL
To change all author URLs one would normally change the author base, however, since you want multiple author bases, we’ll have to do things a bit differently.

Setting two top level domains for multisite
What I basically did was the following: Used Domain Mapping plugin in wp-config.php – Changed DOMAIN_CURRENT_SITE and NOBLOGREDIRECT to $_SERVER[‘HTTP_HOST’] as per what @toscho suggested in wp-config.php – Added: define(‘DOMAINMAPPING_ALLOWMULTI’, ‘yes’); // Allow sites to have multiple domains define(‘SUNRISE’, ‘on’); // Domain mapping plugin activation mapped relevant sub.domain.com to relevant sub.domain.eu The main site can …
Why isn’t WMPL correctly redirecting users based on browser language? [closed]

Front-End Interfaces Without Shortcodes
What you’re doing is, in my opinion, the best way to accomplish this. First off, the pages are a good way to go, because they give users the ability to customize parts of the page like title, meta fields, etc. You don’t have to use shortcodes per se, you can filter the_content for these pages, …
When to use the Filesystem API? Should I use it at all?
