Hey, I was wondering if I could get some help using Blender? I was following the tutorial here: http://www.gamedev.net/reference/art/features/blender2/ But when I go to the UV/Image Select, nothing shows up on the screen. What am I doing wrong?

Nothing, that tutorial is just massively out of date.

In the current version you have to be in edit mode on the 3d view window and the uv/image window will only display the uv maps of the vertex/faces selected in the 3d view.
Also they won't show up until you create them by using a unwrap in the edit mode of the 3d view that again you need to make sure the entire mesh is selected if you want to create a uv map for the entire object.

Ok, thanks. Do you know a better tutorial?

EDIT:
Blender_3D:_Noob_to_Pro/UV_Map_Basics"

thats out of date too, in the current version the edit and face select modes are merged into one
