Richard was most certainly a character and often managed to upset some people; he even managed to get himself banned from the forum on more than one occasion. However, he was very knowledgeable and always ready to help anyone who asked. I used to communicate with him regularly, and still miss his emails, which often contained a joke or several. He suffered from bad health for some time before finally succumbing to his illness three years ago. I miss him too, Barry.
