My questions are:
1- is it possible to have a mix of some languages as a subdomain (de.website.com / it.website.com), and other on their specific domain name www.website.co.uk ?
In this case, does it mean I need to pay the 50$ install cost?
2- I read that only the site owner can edit the translation. How is it defined? by the superadmin joomla user? by a email I will have to provide you with?
Can I register various user / email to get access to the front-end editing?
