I think that's an interesting point to me. We start with a joke, but it prompts me to reflect about the forum's evolution.
This is a private initiative from a particular, Paul, who had both knowledge and generosity to provide a group of people with a tool to share their knowledge on a specific topic (unbuilt aircraft projects). Most of the early members visited different forums but felt enthusiast with the idea of having one devoted to our favourite interest alone. Paul asked some us to volunteer as a moderation team under a list of rules. And that's how it started.
Complains about specific moderation criteria should be solved referencing to the forum's rules. After all that time, that's a quite effective method to solve conflicts. Remember the foundational idea of the forum is about a place to learn and exchange knowledge, nothing else. That's a call for everyone, moderator or plain user.
After 20 years running, the forum has grow in users and expanded in topics. Some of the simplicity of the beginning has been also lost because it seems that new members enter the forum with different interests from that original and core ones. As a consequence of this evolution we have very active members that never post anything in the core sections. Seems that there is a drift that is taking us away from the original course.
If we've reached a point where it feels necessary to vote on a fundamental change to the forum's core purpose, it's because we truly need to split up and no longer share common interests. This forum should remain true to its essence, and those who want to discuss other topics should honestly create their own forum for that purpose, instead of trying to restructure this one. This forum, as I said, was formed by people who participated in other forums. It's that simple.
