Where's the search ?

Where is it ? I want to type in my username and see all posts I've made or another users and see all theirs.

right under where it says
Warcraft III Campaigns Forums > Town Hall > Site Discussion > wateva

to the right of the button that says FAQ

Edit: or underneath a user's post click the search button, and it will show you all posts by that user

Oh cool, thanks alot, this is much better :)
