Thanx dude, it was pretty easy to learn.

I will try to watch some youtube videos now.

That's what I did.

The others are right. It's easy to get started, but once you go through the tutorials, it's dangerously addictive.

Here's one that helped me with work flow: http://www.martinrinehart.com/models/tutorial/tutorial_toc.html

It's good, but there are one or two flaws later in the lesson in some of the Ruby code coordinates. Take your time and you'll see the mistakes. But overall, a great tutorial.
