As I type this, Ken has only posted 1 message (on 3/10) since his return.
I have hopes that Ken will show much more restraint in his postings, and I also hope that the other members will have much, much more restraint in their replies to him.
As far as I know it, Ken is still restricted as before the suspension.
I would also like to point out to Ken, that the moderation efforts at the non "Free For All" forums very much can also be to his benefit. While the "FFA" forum grants Ken freedom from moderation, it also grants the same to the others.
