As I've posted elsewhere, Robert will be sorely missed by all that knew him. I regret never having been able to meet the man.
He's had a huge impact on my life, and on others I'm sure, and he was just such a genuine person, whether helping on the forums, cracking jokes, or most of all being a good friend. I would not be exaggerating to say that he's one of the people who's had the greatest impact on my life so far, and I would certainly not be who I am today without his influence and guidance.
I don't know how to express how I feel right now.
He was a rock to many people, myself included. Always there to lend a helping hand at any time, in any way.
This is a very sad day.
My thoughts are with his family and friends.
