For my latest project I need, for security purposes, to check the details of every user who registers on the site BEFORE I approve them. Dependent on their answers to the questions on the registration form they will either be rejected, approved or approved as members of a privileged usergroup.
Something that has been on my personal Joomla todo list for quite a long time has been a real coming soon page. Setting Joomla to offline mode is OK but it looks ugly and because it requires you to login to view the site you don't get to see the site as a regular user will do.
The web was meant to be read, not squished.
This isn't the way to test a responsive design.
