I added a new feature at Kirnu, which presents images of different internet persons and links to their websites. I made this by addind php code directly to my index file. Immediately, I thought, that this is quite difficult feature to manage, and is likely to get broken with every Joomla 1.5 update.

I have previously tested Facebook, and I even created my own Facebook application last year. (actually there is a very poor Kirnu/Facebook website too) I don't like Facebook that much, but that's not the point. The point is, that if I managed to create a Facebook Application, there is a change, that I could create Joomla plugins too. 

So I searched from Joomla developers site and I found an article:  How to Create a Joomla! Plugin. Looks like I know, what I'll be doing next weekend
