I haven't found a license for the software. I was informed that I'd have to join their forums in order to download the software and presented an agreement for that.

Since I have to sign up as a user (and marketing statistic, since they claim a certain number of registered users as a plus on the site) to download it, I didn't. That means I can't critique the code at all.

The website flies the W3's banner for being CSS validated, but about every page I go to causes CSS parsing errors in my browser (Firefox 2.0.0.13 on Linux).

The providers of WebAPP give "legal and security warnings" against getting their code from anywhere other than from their site. Since they've recently been subject to a spin-off being exploited in a way they say their official version isn't, that's probably fair. Yet another page says that all versions until the most recent of the official branch were remotely exploitable, too.

That same page revealing the pre-1.0 vulnerabilities calls the CMS a "free open source CMS portal", which makes me wonder just what "free" and "open source" license it is distributed under which calls for legal warnings and claims of "piratical spin-off sites" when the code is redistributed.

It may be a very nice CMS, but there are just too many issues with its site and community for me, personally, to seriously consider it.
