[pydotorg-www] Adding User Group Calendar to home page

[mmueller at python-academy.de]

Hi web team,

Since the dates of Python events are split between the events calendar  
and the user group
group calendar it makes sense to add both to the python.org home page.
While the events calendar appears in left column, the user group  
calendar does not.

It would be nice to have the user group calendar there, just below and  
in the same style.

This is the link for the iframe

Thanks,
Mike
