I created a playground acct, then I was in a position to change playground wiki text and save it.
Is that your understanding?
That WAS my understanding, generally, how a Wiki works is that Most pages are accessible for edit by anybody(at least those that signed up) With some key pages that need permission(Home page, key articles)
That's how wikipedia works, as do most other Wiki's, but here people talk about getting permissions.
Either way, I'm well off onto writing it.(In word)
