I only ever met Sven once, at Oztek in March this year, we didn't even get that much time to talk, as I was on the Divetek stand, he was on the Sydney Project / Rebreather World combined stand.
But through the job we both share here as moderators, we've ended up having many dealings online. Sven was always friendly, polite, helpful, and his postings were always well thought out and insightful.
To the two guys who tried to get him back, hats off to you, thanks for trying, you're both heroes in my book.
To Pat, the rest of his family, and all his close friends, my sincerest condolences.
