Change Blogger Blog Setting To Dofollow

I just tried to change my another blogger blog to dofollow.  As internet today spirit is learn and share, let me see the effect of this change.
To change your blogger blog to dofollow, go Design ---> Edit HTML.  Tick Expand Widget Templates.  Find code below,

'data:comment.authorUrl' rel='nofollow'

just delete  rel='nofollow' so the final code will be like this,

'data:comment.authorUrl'

If the result is positive, I will apply this setting to all my blogs.  Just try to comment in my blog, www.dailyconfig.com, and you will get automatic backlink.
