My b2evolution Version: Not Entered

Hi,

I want to change to a PHP file to automatically blog url:

BEFORE:
Explicit reference index.phphttp: / / www.vixioschat.com/Blog/index.php?blog=16

FUTURE:
Path lying index.phphttp: / / www.vixioschat.com / blog / index.php / NAMEBLOG

How this change or especially?

Car currently has a blog that I create manually.

Thank you
