No idea even where to start. I played with creating a 'boring' object a 
while back but I am pretty sure ours is a tad more complicated. All the 
parts of our site I work on are in SQL and was never involved in the 
ZClass News stuff. It just works...and continues to work...but is 
limiting us from upgrading.

So, where to start. Once we get some guidance, we could probably do it 
ourselves.  Anyone willing to a$$$ist? We don't have a budget for it but 
could scrape something together to get started. Even just to log in and 
look at what we have and say,
"Ah, you need to do this and this and this, then it will work."
I know not that simple, but that is what I am trying to find out.
