user profile link on index page

[1master1]

i had a welcome box in index page showing the text

welcome {user}, your last visit, private messages, so and so.... on index page

now i would like to make the {user} text to be linked to that user's profile as when he clicks on that text he must be redirected to his profile.
this happens when we click on the last post users that is displayed forum view in index page.
i tried of adding
<a href="{mybb->user['profilelink']}">{user}</a>
but didnt worked

as like in our forum http://mybbhacks.zingaburga.com/
   

any other solutions?
