I would like some sort of wiki functionality -- where people can edit the same post collaboratively, and I need for site visitors to be able to do a simple authentication to do this rather than having to set up an account and log in. It looks like this might be the ticket, but I can't tell from the cryptic description.
I don't understand your description of this plugin:
"Converts topic and reply authors into anonymous, logged out users"
The comment in the php file reads: "Turns registered users into anonymous users, by creating the necessary post-meta for each topic and reply, and zeroing out the post_author." What does that mean?
Can you explain this in a little more detail, maybe give an example of its use?
