how use wordpess post author's name in post link?

hi,
in my wordpress blog I have different authors, when author will publish post I want that his/her link was shown in post link

for example

mysite.com/author name/postname

 

Your permalink structure (in the permalink settings page) should look like this:
http://mysite.com/%author%/%postname%/

I agree with the point given by above user. try changing the permalink structure.

 

DO as slimrider said. Changing Permalink Structure should do the work.
