OK, because you "went there", I'll go a little further. One of Darrell's posts referenced a new FB site that he's setting up. Also, is he still involved with that Digital Enthusiasts group? Perhaps he's afraid that PN would be competition for both groups? Just wondering. That's the only way that I can explain not stepping aside, to let someone with more enthusiasm run PN.
I would love to be proved wrong on this.
I am not sure there would be a competition per-say. His sites are typically enthusiasts that purchase his books. People also flit about here and there today anyway, there is no such thing in my opinion with "One Forum Only" loyalty. I would find it hard to believe that is the basis, but you never know.
My primary concern is the database.
I tried to collect my posts and have found it next to impossible to find the ones I want in an organized fashion, much less figure out a way to collect them.
Even any images are hard to collect in a simple and easy way.
As for stepping aside, he was never here in the majority of the years that I was here so I find it hard to believe he has some attachment and if he did you would think he would like to see it continue even if he isn't involved.
