It's a pity John has no full access.
In what way?
John has full access to the showcase.
He can start threads.
He can post on any subject he wises.
He can choose to have people tossed out of his threads.
He can respond in a totally off topic manner.
He is free from moderation and can behave in ways that will get any regular member suspended.
In addition, all regular members can enter the Showcase to reply to him only by getting permission and are subject to exclusion at any time simply on the John's whim.
Although John's behavior is free from moderation, all who wish to reply are subject to moderation just as they are in the regular forum.
I would say that EvC has bent over backwards to accommodate John and the only thing stopping John from posting is John.
