Hi,

Sorry I don't have any new tutorials to announce, but I can explain the mysterious Border sub shader.

Organic 2 (and some of the others like Tile, Panel, Skin, etc.) have different zones in the shader and you can shade those zones independently by using the plus button to add multiple sub shaders.  In the case of Organic 2, the Border subshader shades the area in between the zones.

The Panels section of the Getting started with Enhance:C tutorial talks a little bit about the zone stuff in the context of the Panels shader. It unfortunately does not do anything with the Grout shader that corresponds to the Border of the Organic 2 shader, but it may help visualize what is going on.

Basically think of Border as the Grout of Organic 2.

The Octaves slider is tied to those shader zones and has two handles. The left most is how deeply the zones are calculated and the right most is how deeply the border is calculated. This lets you make big zones and still have a rough border.

Does that make sense?
