I wanted expand on the sad news below and share a few stories of our experiences w/ Bill "TFmaster" Koshorek.  I was shocked and saddened to hear the news. That something like this could happen to someone so young is a terrible tragedy.  Our thoughts and prayers go out to his friends and family....

"TFM" and I met years ago at Botcon, (2000?)  I was always impressed with his artistic talent and ambition.  His works graced the table of many subsequent Botcons which we appreciated whole-heartedly.

I remember one instance, years before he started Transtopia, he had e-mailed and asked if we would be willing to host "a few" images of kitbashes he had done.  "Of course," I told him.  Little did I know what I was in for!  (This was before digital cameras had become mainstream and before he had one!)  You should've seen the size of the envelope he sent me!  There must've been 5+ rolls of film worth of kitbash pictures!  The process of scanning, cropping, sizing, organizing all those prints was a daunting task.  One that I procrastinated...

Eventually, thankfully, he got himself a good digital camera and e-mailed us the images.  This time we got them up promptly!  An excerpt from our Alterations Section here:

To me it seemed TFM was always as grateful to have a venue showcase his work (Botcon/net) as he was for the praise it received.  And thankfully, he was not one to hold a grudge and 'let me off the hook' for not scanning all those pictures!  :)

Seibertron.com has set-up a link for donations for his funeral and his son.  We'll miss you TFM.
