web page system recommendations

[real name]

is there any comparing of (free) web page systems?
(wps = something can make page in fuctionality say similar to codeguru - see next)
any recommendations, experiences, opinions?
thanks

i'm looking for something like this:
probably gpl, php and mysql solution
support for article database (title, subtitle, text, author, modif date, ...), article categories (maybe multiply selection)
comments for articles, general message boards, mail notifications
author accounts, user acounts, admin accounts (name, password, hidden email, public short profile text), anonymous viewing
the best keep all in one system (= if possible do not combine just publishing system with just messageboard one)
non-english language users (f.e. will want to make search with or without non-english characters (á should be equal to a))
