[Zope-CMF] CMF Event

[Hans Pongratz]

Hi,

Iīm working on a Zope Project for university and Iīm wondering if
thereīs a possibility to give a CMF Event more fields.
e.g. I want fields called "Building" and "Room" within the existing
onces.

Should I register a new Product or can I "improve" the existing CMF
Event anyway?
I search on the internet quite awhile and havenīt found a "good"
documentation for CMF for my problem. Do you have any hints?

Thank you very much
