I like Wordpress, but that's all I know right now. What is your favorite free script, and why?
Wordpress is the general favourite IMO,
I have also had much success with TextPattern
Don't forget to visit http://www.opensourcecms.com/ , as they have a large array of opensource blogging systems for you to test out.
Does textpattern come with sef urls or is there a mod for that?
If you like 'em simple, try Blosxom
Can anyone here show me some of their sites that use textpattern?
