Please, PLEASE, P L E A S E have a printed manual.
I find it impossible to follow instructions given "on screen" because I have forgotten what was suggested by the time I have gone back to the application.
There is a series of books "The Missing Manual" which would NOT exist if people did NOT want a printed manual.
I appreciate that lots of people don't want a manual.
My view is that if somebody is selling an application (for hundreds of pounds) the additional cost of offering a printed manual would be infinitesimal - especially if it was supplied on request rather than "in the box"
Of course that argument does NOT apply in the case of Groups.IO
