The Internet Society offers various online courses.
The latest is "Building Community Mesh Networks" :

The course was developed by IEEE and ISOC.
Many of the course participants are IEEE SIGHT, IEEE Smart Village  and HAM radio folks.   
It is an open course but you must have a ISOC Membership login  (free => internetsociety.org)

There's an online registration form with instructions. 
The course is self directed but has a six week completion timeline.
Space is limited - sorry for late notice but I got a late start on it myself.
I think after the course is over it will be left online.
