I haven't the foggiest idea. However - As Joe has informed you multiple times already - he has given you all the information he is at liverty to provide. In order to obtain more you must contact Max off forum. How much clearer can it be to you?

If you went to your local council office and asked a question re: a regulation and they informed you they were not allowed to give you the information - it could only be provided by a personal visit to the regional office - would you continue to walk into the local office daily demanding an answer?
