This post on edx-code made me realize that we are not particularly careful to make references to Edge context-sensitive for partners only.
It also points out that we are inconsistent about how we refer to the two web sites...
Check the Open edX course team B&R for references to the two web sites, make generic (those sites are for partners only, use the only:: directive to provide a generic alternative)
Ditto for learner guide
I searched for 'edge' in the Open edX B&R guide and Learner's guide. I found only one place where I wanted to make text conditional to partner only.
