So I'm going to show my inexperience here, but I have to know.

What do the decimal integers mean on the snakes in peoples signatures and elsewhere? I'm referring to things like this:

1.0.0. Regular BP
0.1.1. Spider BP
1.1.1. Blah
0.0.1. Schmou

Of course I know what "regular" and "spider" refers to, but what do the integers mean?

Just a question.
