Download Joomla Templates

Any Good sites offering free Templates and Extentions/Components / Plugins for free for JOOMLA ??
Even Forums will do….

First port of call will always be joomla.org as all extensions tend to be listed there – thats how people find out about them:

http://extensions.joomla.org

From there most extensions link to their own site / demo page and others simply have a sourceforge development site.

Some have heavily visited forums and a good daily level of support because they are so widely used eg.:
Community Builder @ http://www.joomlapolis.com
or because they adapt joomla to function as a specialist website eg.:
Virtuemart @ http://virtuemart.net

There are many other great sites for ‘empty’ basic templates and extras such as:
Compass Designs:

http://www.compassdesigns.net

or Rocket Themes:

http://www.rockettheme.com

Good luck!
