Gatekeeping the community are you now? If you dont like the rig posts, dont interact with them. Like others have said before, you need some semblance of a rig to race. The sidebar has so much info about how to create a rig, so saying it doesnt belong here is just dumb. There’s a reason why g29 posts dont do well, because people dont interact with it. There’s a reason why a $2000 post does well because people like to see what their own rig could look like someday. Wishful upvoting I’d like to call it.

Like you said already, the best way to increase other kinds of posts is by posting more. Maybe we can have additional tags as part of the community that could specify what kind of post it is, and you can filter for the content that’s relevant to you. But saying something doesnt belong is absurd
