MikeCL Hey, I haven't removed any tags, but I have tried to clean it up a bit and place them where it made the most sense. Would you like to have 3.x, 4.x etc in the Community primary tag as well? I think it makes sense for it in the Help tag. But if it also makes sense to have these in the Community tag, I'll look into it.
We(mostly I) previously moved most tags into secondary tags once we had moved on to flarum. This way they can be mixed and matched more and used in all categories('primary tags'). That is, outside of help category. Imagine posting your project to projects for an example. You might want to use many of the same tags there.
Only one I hadn't finished moving to secondary tags was building I think, and I had separated it from 'building, exporting and optimizing' into separate tags. So what I had left to do was manually go through every topic in help/building and re-tag and categorize properly.
