This is great to see! The audience for this is a really important element of this project.
The Facebook groups for Factory Five have become the random question zone. Also, there are several (at least 5?) groups that all overlap and do not provide the readable log and learning that we see in the Forum entries.

We need a modern site for Factory five builders to discuss and have a good information source. Searching on the old Forum has become a hassle but is still better than Facebook, Instagram, or others.

Have you talked with some of the active, young or new builders about the forum compared to Facebook? I bet some of them don't even know the forum exists.
I think the Build log is the core of this as the questions and answers all need the context of the build.
I like the idea of milestones, but these will vary with vehicle. Also, the order is usually not linear. These could be filters for a thread as well. Maybe its a combination of topics and milestones we can use to categorize a topic for search.

I think that a flag for Safety related items could be useful as well. Steering, Suspension, or brake issues where either instructions or components don't work as designed or maybe expected.

I applaud your efforts. Change is hard.
