Yes, there or on jupyter.org
We know we are bad at communicating. If anyone reading
want to contribute and is afraid of coding, writing things like
that on the website would be a perfect way to contribute
and would be of great help to everyone.

Not silly at all. 

You can perfectly run IPython 3 with Python 3 and kernels on Python 2. 
for the time being you will need to install IPython notebook with python 2 and issue a

$ ipython2 kernelspec install-self

This will make the IPython2 kernel available with IPython3 server running on python 3.
