When building a new website, you often don’t want the public to see your work as you are developing it. We’ll I have created a video that shows you how to put your site ‘Under Construction’.
This uses the ‘Under Construction’ plugin by Jeremy Massel that you can find here:
I prefer under construction plugins vs under construction themes, because it let’s you work on your site, while hiding it. Another good under construction plugin is the one from CSS Jockey here: http://wordpress.org/extend/plugins/custom-coming-soon-page/ It’s a little fancier, and you can add custom graphics to it, but I prefer the first from Jeremy Massel only because it’s faster to install.
