I just posted the first drafts of my character modeling tutorials on the community wiki. They are:Building Textures with GIMPBuilding a Character Mesh in BlenderTexture Mapping Character Meshes in Blender
I'm still working on two more tutorials to round out the selection: skeletal animation and exporting the object for use in CrystalSpace. They're currently scribbles in a notebook... I'm working on doing screen captures & typing it all out.
Feel free to provide feedback and correct any errors - I'll update the tutorial likewise.
