I'm away from my 6.6.2 install(s) at the moment, but I'll take a look at little later once I'm home.

Try taking a look in the Back-Office under 'Site | Site Settings', you should find the 'Plextro' navigation item listed there.

What I can't find though, is a way to turn it off, only change what it says. The rest of that menu is made up of links to the collections themselves, which are all listed in the 'Site' dashboard. Beyond that, I'm scratching my head a little.

Right now you would need to duplicate the skins_site files into skins_site/custom and make modifications in the files there.

Kind of old school.

Of course we will have a GUI for editing this easily in an upcoming release.

thanks. found it in _site_body_header.inc.php although i modified it in skins_site and not skins_site/custom

The purpose of using the custom folder is that you won't lose your customizations when you upgrade b2evolution to the next version.
