Expanding on Plone User Manual with additional use cases

Getting them technically done is explained well in the existing manual,
and examples provided here as points at the end of this page:

http://plone.org/documentation/manual/plone-3-user-manual/managing-content/folder-view

I'm however getting common requests from different users, who seem to
have trouble converting it to their use cases.

The request for my users (government/NGO project websites) usually
revolve around "collaborative spaces" use cases.

* Joe want to put up drafts of documents for feedback (comments).

* Jane wants to create a wiki (usually they just mean enable Sharing)
  - container folder, wiki markup, enable comments (talk), history

* Joe and Jane, want to collaborate on a workshop event, where
  they would have a shared folder to collaborate on pages such
  as agenda, schedule, news, event item, photos and maybe video
  gallery
 
I'm wondering, is there a place (or need) on Plone.org for step by step
illustrated guide of examples in same style as the user manual to put
these up?

Would Examples in the existing manual to expand on the points at the url
mentioned in the manual be appropriate? They're kinda like programming
recipes, except for users.

I'm already working on these for my users, and would love to contribute
them to plone doc efforts if possible.

Regards
