Improvement!

I'm amazed with my own technology improvement lately. I am kind of person who dislike complicated things - computer is one of them (though humans create computer to simplify their life). But to be very honest I don't know JAVA, html, or whatever it is, seriously I'm not trying to be proud of my stupidity. But lately, I upgrade my blog with some lists and slideshows. I know they are small things, but finally I made it! (though till now I don't know how to change my header). JIa you! And please guide me :)
