Review: GCalendar, Google Calendar for Joomla
GCalendar for Joomla is a great extension for displaying a Google calendar on a Joomla page or in a module position. Of course, if you have Joomla configured to allow iFrames, you can easily inset the Google Calendar iFrame code, but this method does not allow you to configure the calendar colors: you’re stuck with the Google blue outline of the calendar.

Joomla’s new Save as Copy feature (starting with version 1.6) is a great time saver. Before Save as Copy, in order to copy an article, menu item, or module, you had to first create one of these items, save and close it, use the copy function, and the copied article. Now, with Save as Copy, you can create a new article, click Save, and then click Save as Copy to create another and another and another until you have all your articles and menu items built. This is a very fast way to get a site up and running.
