So sad to hear. He will be very missed.

My deepest condolences to his family and friends. Robert often stopped by just to say hello and I find myself deeply saddened to hear of his passing. Rest in peace and know you will be fondly remembered by the many you touched.

I'm so sorry and much sympathy to his loved ones.  He was so nice to me and such a great friend. I'm shocked and saddened and crying.  He was GA's example of life and how it should be. RIP my friend.  You were awesome!

Oh no! Wow... I'm shocked... May his soul rest in peace.. :*(

Rest in peace, Trebs.

As others have said, this is very sad. He was a good man. The world needs more people like him, not fewer. My condolences to his family.  

Rest in Peace Robert!  You will be remembered. 

I'll miss him. He was one of the good guys. If you know me well, you know I don't say that about just anybody.

There is so much to say

But so little words exists

Goodbye's not enough

But it's all we have

So goodbye Robert

You will be sorely missed

the world turns grey and shrinks yet again

the keys that unlock my door to the outside blur and avoid my hands

a cold chill passes through as I think of the souls that have paid the ferryman

with hope eternal, that all that have enlightened my world, have had the fare

May we all meet Robert (Trebs) again on the other side of the river

R.I.P.

A beautiful star bright at night that will continues shine.

I am so sorry to learn about Robert's passing. I had no idea he was sick. The few times we communicated with each other were good times. He seemed like a gentle soul. RIP dear man. 

I'll always remember Trebs by that beautiful picture he had with his big dog laying on top of him. It always made me smile.

Trebs knew everything about the site and he was always there to answer my stupid questions. 

I am so sorry this happened. My heart goes out to his family and friends, including all his GA friends who knew him so well.

Rest in Peace, Trebs.

Prayers and condolances to all who have been affected by Trebs tragic passing. He will be remembered and greatly missed by so many. Rest in peace. So sad to see someone so young go.

This is very sad.

Rest in peace Robert. I didnt have the chance to know him much but the only time we chatted he was an awesome guy

I'm incredibly stunned by this news. He struck me as a real fighter when it came to battling this, so to suddenly hear that he's passed...I can't believe it.

R.I.P.

That is so awful.  Speechless.  Just speechless. 

A very sad farewell to a man who always knew how to be helpful and funny and did both often. Like Lisa, I will always remember the photo with his dog lying atop him looking happy and loved.

Such a good man. He'll live in the hearts of everyone who knew him. <3

RIP Robert, I'll miss him.  He was a good friend, always talked to everyone. I'll pray for his family to be strong through this hard time. 

Rest In Peace Trebs.

 I'm sorry to hear this. Rest in peace.

I didn't know Trebs as well as I would have liked, but I am deeply saddened to hear of his passing. Rest in Peace, Robert. My condolences to all his friends here. These things are never, ever easy. <3

Times like these, I find myself compelled to quote W.H. Auden's Funeral Blues, because I think it describes so very accurately how it feels to lose someone you love.

'The stars are not wanted now; put out every one,

Pack up the moon and dismantle the sun,
Pour away the ocean and sweep up the wood;
For nothing now can ever come to any good.'
