Hi,

I want code for blog to implement in a website for example like in http://blog.directorymaximizer.com/. New post should be in top and it should have archives on monthly and yearly basis and each post should have category.
Is there any website providing this kind of code for free. By using php and mysql is it possible.

Is there any website providing this kind of code...
Yes, plenty of services can do this

...for free
possibly .. try search for "free wordpress templates" :)

Looks a whole lot like wordpress and if you look in the coding you can see this:

<title>Directory Maximizer Blog</title>
<meta name="generator" content="WordPress 2.8.3" />

Ok Thank You.

Could you please explain me more on this.

Wordpress is a free cms you can find it here: http://wordpress.org/
