Allowing anyone to post?

That’s me, by the way.

No, because how would wp know who to credit the article with ?
If you do want to do this, create a user for that purpose and advertise that.
“Login with the name “poster” and the password “poster” to write something here”
That sort of thing.

Yes, I can see the potential for problems – like if poster/poster was ten people trying to post at the same time. Perhaps I’d better go the registration route after all. Thanks, podz. ??
