Say I've got 100 or so domains and I want to have them all have their own, customizable content, but have the same backend... what's the best way to do this? Multiple Domain module with Drupal, or use wordpress or some other CMS? I'm pretty sure that both of these allow you to spread one site over multiple domains, then customize them, but I'm not 100% on that. Thanks in advance, hopefully this will help others with toooooo many domains as well
DRUPAL should be good option if you want free one. You may also try ExpressionEngine, but it costs you money.
Joomla is another good option. Inserting, Editing, Removing content, pages are too easy in Joomla and its free.
