The mailing list for P5EE can be subscribed to here
. As for the documentation, well that too is fairly lacking at this point (excepting a few PODs) - I suspect that much of the discussion of development directions is taking place on the mailing list and so will be watching it over the next few weeks before posting to it.
The different colours for code within the P5EEx development tree is intended for the separation of different development threads - Currently, there only seems to have been any real activity within the Blue and Orange thread.
