I asked him that very question one time. I think he said something along the lines that this site was already enough to keep him involved enough, he didn't need more sites to keep active in the hobby.
I miss Hans also, we had sort of a friendly opposite thing in our posts,,,,,,,think Hasegawa vs Monogram, Enamel vs Acrylic, resin vs home made,,,,,,,,,wow,,,,,,,what did we agree on??,,,,,,hah,,,,,,,,,oh,,,,we agreed on enjoying plastic model building
I am sure he will be back whenever he gets his real life stuff all sorted,,,,,,,,sometimes we all end up too busy to post even once a month,,,,,,I remember being thought of as an MIA on MM once, because I hadn't logged in anywhere for 3 or 4 months,,,,,,,,Anne was getting emails asking about my health, I had been busy so long
