@mk Many of your recent questions are not specific to !andstatus, but are about Android design and terminology.
I agree that some users may only start learning Android via figuring out how AndStatus works.
This is exactly why we created FAQ for in a form of "Questions" in the Issues section https://github.com/andstatus/andstatus/issues
As I see it now, User Manual will not be too long, but it will have links to these Q&A, allowing not only to read, but to ask and to take part in discussions.
There is a ticket on a User Manual enhancement https://github.com/andstatus/andstatus/issues/229
