This notebook convert a mailing list (or a set of mailing lists) into a network of interaction

What it does: -it creates a network of interaction between senders and receivers of emails, on one or more mailing lists -it generates a .gexf file that can be imported in Gephi for visualization and analysis

Parameters to set options: -it can look in one or more mailing lists, according to how many urls are set in the ‘urls’ variable; networks are aggregated across mailing lists -it can filter the network by date; set the variable 'date_from' and 'date_to' with a date frame consistent with the data

Set a valid date frame for building the network.

#The oldest date and more recent date for the whole mailing lists are displayed, so you WON't set an invalid time frame
