There are some issues with the display (css and/or tpl’s), and options in the main menu wich are not working (periods, assignments, etc.)
I’ve never been able to use them because Im afraid that jreyes didn’t finish coding them (or there must be some hard coding needed?).
Anyway, but I installed on a proposals/4.x, and created a ws type course, and then, personal ws for me as user who just joined that worksapce, and it worked!
Great, so far...
