I think it is consensus that we don't want a solution that is based on 
IAdding or an other view called '+'.

The example http://www.example.org/guestbook/+Message has nothing to do 
with that. It means to reserve names *starting* with '@@+' or '+' for 
CMF add view names. Similar to the 'add' prefix convention encouraged by 
z3c.form. Right now I prefer this solution, but I have to think a bit 
more about the pros and cons.

The other possible solution (and the one with most spontaneous +1 votes) 
is a CMF specific add view with the generic name 'add'.

Cheers, Yuppie
