Using forms in a website to let the user register is pretty common these days. But what happens when you want several input values of the same subject? It's pretty ugly to make 20 fields with "I can speak the following languages:". Those users that can only speak one or two languages would leave a big empty space and would have to scroll down a lot. Those users that can speak more than 20 languages can't input everything they want.

In this example, what you want is that the user can give an input and dynamically expand the form. This can be achieved with the help of JavaScript and here I'll show you how.

This isn't going to be a long article, since I don't have much to tell about this technique. Just check out the demo, look at the code and learn for yourself. I added comments to make it a bit more easier.

!JoomlaComment is one of the leading free commenting components for Joomla!. I've been using the component since the beginning of my website.

Still, !JoomlaComment isn't perfect (yet) in my opinion (And I'm not the only one). I would really like to see Trackback support and the ability to edit your own post in 120 seconds. For my website, I wanted to add Gravatar support, so I went editing the !JoomlaComment code to show those globally recognized avatars.

One of the strangest things is that !JoomlaComment already supports most things needed for Gravatar. There is already avatar support for Community Builder. The only thing needed for support Gravatar on a PHP platform is an email address. !JoomlaComment has the build-in functionality to ask the user for his email.

So let's edit the PHP code and let's add Gravatar support! This tutorial is written on the latest release of !JoomlaComment at this moment: 3.23.

It's been a while since I wrote my last Flash / Actionscript tutorial. But lately, I got several requests on different Flash tutorials so I decided to start up the program once again.

Many websites don't want their images to be copied. You can add a (hidden) watermark, slamming your logo several times on the image or let it carry a secret file, but I wanted a totally different approach. I wanted to protect my images using Flash and more important: It should be done dynamically.

Before I'm going to start with this tutorial, I recommend you to check out my demo on what we'll be creating. I'm telling you: Those images are loaded dynamically using external JPG files. Can you find the real images?

You can download the source and demo code if you don't feel like following this tutorial. You'll only need to change the XML file and you're done.
