I got a lot of spam from the Joomla contact form, I need a captcha plug-in. Actually, there are a lot of anti-spam plug-in in Joomla. But they are fairly complex, some of them even have a custom-build contact form. That is too much.
After I spent some time to research on the internet, I found a plug-in calls Joo ReCaptcha. That is very simple. After I installed that, the contact form will have ReCaptcha image under the input fields. That is great!
I got a new website which is using Atahualpa 3.6.7 wordpress template. Yesterday, we tried to place an Adsense code in there. It doesn't work. We believed the website were blocked by Adsense.

That is easy.
Joomla is using the MVC Pattern. There is another feature. You can override display function in controller to trigger whether the controller will display the template. In the following example, I will not display the template when the form is submitted.
