Joomla is a great piece of software, and the developers are deserved allready full support for keeping it evolving. One of the easy methods are to keep those Powered by Joomla texts and messages in place, and visible. But what if - with good reasons - you want to get rid of those? For example to make less obvious for Joomla-hackers to identify your site as a possible next target - to name only one of possible multiple reasons. (Read also this article about how to remove the Generated by Joomla! tag!) Or you may want to keep it, but a bit tweaked, to reflect better your contribution to that site of yours. The same questions are arising: where that footers are coming from?
As you may allready know, lot of things are much simpler in Joomla 1.5. And you guessed it - here the situation is the same.
So, if you want to disable the footer with copyright message go to Extensions >> Module Manager and unpublish the Footer module. Done! Easy, eh?
If you want to personalize it, the task is a bit more complex - you will need to make your hands dirty with code. Here's the recipe - assuming you want to change the English version. For other languages the solution is same, just replace the language codes with yours.
So, grab your favourite FTP program and go to the language/en-GB/ directory, edit the file named en-GB.mod_footer.ini and change the following lines to suit your needs.

In Joomla 1.0 the situation is more complicated. Generally the code displaying the information is embedded in the template, so no general rule of thumb can be set up. However there are couple of informations you can use.
The simplest way to include this information, generally used by the template makers is something like this line (found as is in the default Joomla 1.0 template, Rhuk's SolarFlare II)
<?php include_once( $GLOBALS['mosConfig_absolute_path'] . '/includes/footer.php' ); ?>
If this is your case you need to get rid of this line, or edit and tweak the /includes/footer.php file. But not allways this can be accomplished that simple. In Joomla 1.0 you had no better choice, but to examine your template, and find out how the template builder has inserted the information in the one you use on your site.
