Custom Content Page

The Custom Content page allows you to edit some of the common types of information that you can add to your web pages:

Notes tab (4 provided) - edit the content that is added via the Notes information blocks. Add these to any page by clicking on Page Settings and then dragging and dropping the appropriate content type from the menu on the left to the content area on the right.
Noticeboard tab (4 provided) - works similarly to Notes (above).
Site Footer - Edit the text and/or images displayed at the bottom of every page.
Social Media - Add links or feeds for Facebook, Twitter, YouTube and LinkedIn and then add these to your web pages via the Page Settings.
