How to add a GeoGebra Dynamic Worksheet to a CMS / VLE (eg Moodle)
You no longer need to use the Moodle filter for this
From version 3.2.31.0 GeoGebra can export a standalone html file (ie no separate ggb file)
From version 3.2.45.0 the keyboard shortcut Ctrl-Shift-M copies everything you need to the clipboard.
File -> Export -> Dynamic Worksheet as WebPage now creates a single html file (ie no ggb file needed) which you can then paste straight into eg Moodle (turn on html editing when composing a webpage)
Depending on which CMS / VLE you are pasting into, you may need to delete the html outside the <applet>...</applet> tag and you may also need to delete mayscript="true"
In the advanced tab, you can even put the html on the clipboard to make the process even faster (select Clipboard: html at the bottom right)
You can also select Clipboard: Google Gadget and Clipboard: MediaWiki as appropriate (MediaWiki extension detailed here: http://www.mediawiki.org/wiki/Extension:GeoGebra )

In GeoGebra 4.0, the process will be simplified further with a Ctrl-Shift-M option.
