[ZPT] An easier question ...

Evan, sorry I accidentally sent my reply to you rather than the list a
minute ago. I'm sending this now to the list.

Well, I'd vote for it or something like it.  Thanks for your response and
for the example regarding having globals defined in the macro and used
below that macro's use.

Can I have your opinion on whether you think it would be "smart" on my part

to go ahead and build my new site for a roll out in a few months based on
ZPT?  In otherwords ... do you consider it production ready enough?
Although it's changing frequently ... should I be able to trust the changes

will either be backwardly compatible or at least not too much of a
nightmare to change?

Thanks,
Lynn
