Danielle,
So you find that Php-Nuke has a higher quality than Mamboserver (MOS)?
With all respect to you I still say, "Yes I do..."
Exploited? I am not sure what the exploited is all about but Problably comes from the ability to create awsome looking sites and the availabilty and the ease to install themes and add to them. I have a private community site and I have done alot of kewl stuff with it so far.
I have looked at all of the links you provided and I do admit that they are some nice looking sites. Nothing wrong with them. But I am looking for the so called

expolited abilities that Php-nuke has to offer. It may be just my personal preferences that makes Php-nuke the higher quality because of it's abilities. I am sure others will feel the same if they are using nuke. Because it may seem it is expolited to some it is wrong to use that a reason to take it away from others.
Here is a site that gives some ideas of what php-nuke can do.
SAMPLE SITEMambo and the others that are left on the list are not my style!
