@tinyrabbit In the original C2 wiki that's what happened, but there were no "admins" or "advanced users". That was fine in a small community, but it's abundantly clear that wider access needs to be controlled. Heavily.
People don't like to be censored, though, and don't like their words to be changed, and their "contributions" to be discarded, so there are problems.
And now people say: "But we have wikipedia ... why bother?"
But yes, to all you've said.
