It does what it should do AND makes it so simple for the user to use that this plugin sets the standard.

Edit article, select position in article, click on the "Module" button at the bottom of the article content edit pane, select the module you want to insert from the pop-up window and you're done.

This is a great extension.
Very simple to set up and to add additional form fields. During config it even identified a small change I needed to make to my template in order for it to work with this contact form as it should.

Good CAPTCHA implementation has reduced my spam as well. Another really cool feature is that all messages sent are stored in a DB for later review etc.

I love it.

This works great for me.
I can now write content in an article and include external web content (like my gallery) whilst having enough own text for search engines to find the page (unlike standard Joomla! wrapper that does not allow your own content on the same page).

I have modified this plugin to:
1) enable auto height slection as per Joomla! wrapper option. For content hosted on the same domain as my Joomla! installation the iframe plugin can now automatically adjust to the correct height.
2) enable URL parameter passing. I can now pass parameters to the iframe URL by adding parameters to the main site URL.

I'm not sure if I should mail the modified plugin to Nguyen or if I should publish it as a modified version of this extension?
