The problem would be human resources to implement it on the doc site;
I don't know how PHP people control modern spammers.
The current, Pythonic way would be to edit the tutorial when inspired. However
http://wiki.scipy.org/Tentative_NumPy_Tutorial
reads: "Please do not hesitate to click the edit button. You will
need to create a <http://wiki.scipy.org/UserPreferences>User Account first. "
which leads to http://wiki.scipy.org/UserPreferences
"UserPreferences
You are not allowed to view this page."
