I think it is one of two possibilities with RP.
1. After losing his job he may feel a little angry at our forum. Not the people mind you just the forum itself.
2. He may have made and agreement with his employer to get his job back, which I am sure would include no longer talking on this site, which would be monitered.
On the same note, perhaps his employer has take more drastic measures and RoadPizza has received legal advice , telling him to avoid this site until the matter is resolved.
Lets just hope everything goes well for him....
