After being appointed a moderator here late last summer he only made 20 more posts during the fall, and then seem to have disappeared altogether in the middle of November. He still posts at morphzone.org and amigaworld.net, so look for him there if you want to contact him.
I don't think this relates to him, but many people has been upset with the actions and behavior of the new owners of this site during the years since Wayne sold it, and the drama they chose to project on it, with secret owners and yada-yada, how they used the site for their own agenda, and a lot of other things. Many people left, like Jens Schönfeld of Individual Computers, and when the site owner decided to simply switch off the site because of him getting angry with something or whatever, it caused
many more people to leave (most left silently though without making a fuss about it, they simply stopped posting, if you think about it there are many "names" missing here today).
But again, I don't think that's related to amigadave.
