I was busy trying to add the Twitter-application to my Joomla site so if a visitor visits my website, it will be viewable directly. But what I tried myself, I couldn't make anything work.

On the Joolma-forums there was a member who actually asked it himself, and he got the only working method:

- Add a new 'Custom HTML' module.

- Fill in and enable the necessary options what's asked.

- Add in the 'Custom HTML' the html-code what is generated for your username.

- Save the Module. If you're refreshing the site, Twitter shows up.
