In my opinion it would help if useful instructions how to use such services won't look like an API documentation for developers.

Your idea of having people in your family/friends that help everyone else with joining such communities is nice, but it also depends on some factors: - Do you know such people in your family? - Do you have a family/friends? - Do you want to waste their time with your needs, and how many people must be served by one person?

It may work for some to many people to ask for help with something like this, but not for the masses I think.
