Good work with Help:Manual pages. I think it's an excellent idea. I've seen a lot of mediawiki communities out there which would benefit from a little copy & paste of help text.
I've created a page "Public Domain Help Pages" to describe the project (moved your description here), and linked to this from the Documentation page. Hopefully that will help this to attract more contributions.
We can discuss the project here
