ChetanTiwari on "Permalink in wordpress"

Hi All,

How can I rewrite a permalink in wordpress
I want to use user login name in wordpress url.

domain-name/page-name/uname/user_login i.e

domain-name/page-name/variable-name/value-of variable

or

domain-name/page-name/user_login i.e

domain-name/page-name/any-value

In place of

domain-name/page-name/?variable-name=value-of-variable

Can anyone help me out?

Thanks in advance
