[afnog] summary document mailman cross-server move

[Hervey Allen]

Since I was taking notes...

I've created a document that describes the details of moving 
the afnog at afnog.org mailing list from one server to another. 
Getting the steps right required a few iterations.

If anyone has suggestions about doing this differently I 
think that could be useful information for the list.

The document is here:
