By the way, you (and all of the new guys, and perhaps even some others) should name your nodes! Give them a cryptic title of what they do. You'll find that the more you work in TG, the more nodes you'll be using, and after a while you won't remember what you did where. Especially if you open a file after a year or so, and they all have their default names, you haven't got a clue what it was for.
And locate them in a neat, logical and orderly manner across the network.
Also, hide nodes inside others they feed into (select them, CTRL+X, rightclick on base node; edit internal, CTRL+V once you're inside the node, go outside again and rightclick on the little triangle inputs, and select the appropriate internal node, after which the triangle will dissappear). That gets rid of a lot of clutter.
