Get more forums for your forums... Get rid of that stuff at the top and have a little less to scroll through. Add the following to your Stylish custom stylesheet:
#globalnav-search { display:none; visibility:hidden; }
#adobe-header-forums-breadcrumb { display:none; visibility:hidden; }
#globalfooter { display:none; visibility:hidden; }
Good news: If you're logged out, there's a login link still visible in the upper left.
Building on Eric @ MCA's Adobe Jive Forum style override (see his original post).
Edit: don't need the footer either. :)
