How to remove or change the default OA branding

Out of the box Open Atrium is shipped with default branding;

1. The logo next to the main menu
2. a Powered by Open Atrium image in the footer
3. An image (2 images actually) at the login screen.
4. A default home page

Of course, it's also easy to override all of this in your site-specific theme, so if you create a subtheme of oa_radix you can add/remove whatever you want.

Adding your custom header and footer minipanels

Create your own Mini panel from scratch and then go into the Space -> Config -> Variables and in the Layout area you can specify the machine-name of the header and footer mini panels you want to use. These will inherit to subspaces, so if you do this for your top-level space it will use your mini panels instead of the defaults.

All links below are in the admin menu

1. The Logo next to the main menu can be changed in the Open Atrium -> Config -> Banners area
2. The footer is using a Mini Panel. Go to Structure -> Mini Panels. Edit the Footer, choose the Content option and click on the gear wheel hide/change/remove the "Powered by Open Atrium" widget. If you remove it, you can replace it with a custom block containing your transparent image.
   
   
3. The login page is a Panels page. Panels Pages are in Structure/Pages. Go to the General tab on admin/structure/pages/edit/pm_existing_pages-user_login. In the general settings for the panel there is a CSS class of "oa-login". Edit the panel and remove that css class and that will remove the background image.
4. To change the default Open Atrium home page, copy the template file from profiles/openatrium/modules/apps/oa_home/oa-home-default.tpl.php to your sub-theme. Clear all caches (Admin->Configuration->Development) so that the template override takes effect. To add more content, an easy way is go to /structure/pages/edit/page-oa_homepage. In Anonymous Home section click content and add content (similar to a normal Panopoly page).
