I used all of mrmidi's tutorials on the wiki and can now do everything I need to make a terrain so in that regard it served it's purpose.
Nothing wrong with a bit of trial and error either. You won't make a perfect terrain first go it takes a little time to learn just like the game does but you will be suprised at how enjoyable it can be once you start letting your creative juices start flowing.
Start moving mountains and making rivers and you will feel like GOD!
