Re: Adding modules side-by-side in module zone
To get the full-width topbar, you can change the "Site layout" on the Look & Feel admin page (tiki-admin.php?page=look). The "Fixed_top_modules" and "Social_networking" options will do the trick. The first one is what is used at this site. It displays the top zone and the topbar zone. The second displays some info automatically (site title, etc) and the topbar module zone's modules.
