Here is a list of the scripts you requested, with some comments of
what are the used for and my opinion in most cases. As you can see,
the list is long, but please, don't hesitate to request more detailed
info on any of them.
It's a very simple web log, just to publish news, it's like the news
module of Postnuke.
Is a fork of b2, they have taken the source code of b2 and have
developed a new version, adding features, but without leaving the
simplicity of b2, that is, it's just a blog, not a full CMS (Content
Management System) as phpnuke and postnuke are.
This is just another weblog, in the feature list there is nothing new
or great on this.
Another weblog, but with more powerful publishing features, but note
the "Free" word, there is a free version with limited capabilities, is
suposed to be for personal, non-commercial use.
This is an evolution of b2, checkout the about page
Drupal is general purpose CMS, very powerful but a bit hard to use by
novice users, please, check out this other answer of mine to know more
Another CMS, without any originality, more of the same, I have used it
in the past and I prefere to use any kind of nuke, this script is not
updated very frequently.
The first CMS to be famous due the easy of use and installation, well,
I answered a question about it for you, what more can I say ;-)
A fork of phpnuke, with the purpose to make it more secure and more open.
Another CMS, but developed by a university, in my opinion is very
primitive, but the main feature is that is XHTML and WAI compliant.
A "more-of-the-same" CMS.
Yet another CMS, nothing new on the feature list, but the main feature
is that the code is OO (Object Oriented), that means that the code is
easy to maintain and expand.

The best forum software ever made, fast, with a lot of customization
options and integrated in the most used CMS.
Another bulletin board, but they require to pay if you want to remove
A shopping cart, but without reach the features of osCommerce.
The perfect solution to run your virtual store, it has a lot of
modules that provide almost any required functionality
A script devoted to let you build an image gallery site
Another gallery script, which seems more professional than the previous one.
Allows you to run your own mailing list without require you to use a server.
A great software I have used/customized in the past, still some
features missed (for example, full project recolocation), but the best
of current solutions for project management on the web.
Is less featured than dotProject and much more ugly.
