OK, thx for the info. So we will be able to use Zope 2.13 with the 
techniques mentioned before? That will give us another two years to 
think about going on with different styles. So basically Zope 2 will 
be the framework for Plone only, because the community which is/was 
using Zope 2 for standalone individual projects has decreased to nearly 
none. So it might be a good idea to look for something completely 
different? I don't think that Plone will be able to do everything we 
want it to. Or do you think we can stick with Zope 2 but change the way 
of building applications to ZPT/TAL? So we have to get rid of all DTML 
and what about an alternative to the ZSQL Methods?

I do agree.

OK, i have subscribed to the mailing list today, so unfortunately 
i haven't found this sort of information anywhere else. I don't want 
to blame you or anyone else for that, but it's not nice to hear that 
right now :-(
It might has been too confusing in the past, with Zope 3 being such 
a mistake and of course i haven't really checked whether to change 
something or not...
