PHP/PostNuke can be nice indeed, but ofcourse the customizing/adding your own scripts takes lots of time and effort; if your site needs a lot of features PHP/PostNuke/any CMS doesn't offer, <b>and</b> you have the knowledge and time to make your own CMS (in NGEmu's case, that's "Bobbi & friends"; don't count me in though

), you'll understand the latter is preferred.
I think that may be the problem with standard CMS's: they're mostly used by people who don't want to put too much time in it. There aren't many people who do, probably cause the pros (not saying you aren't one of 'em Wormie

) often prefer to make their own CMS as long as they have enough time. And as passive said, it's the cheap PHP/PostNuke sites which make the better PHP/PostNuke sites out there look like "not worth checking"...
