I had checked in to MTBR once in a while because they have grat info on the discussions about the parts on their bikes. Their IGH discussions and pics were especially helpful.
At one point, I noticed they had created a new ebike section, so I joined and posted that I would answer any questions that newbies might have. One responder asked "why am I here?" even though I was posting in the ebike section. To be fair, he might not have known about the new ebike section, and was just skimming new posts.
The most consistent concern was that wild riders hooning would get some of the mountain trails shut down, after it had taken a lot of time and effort to open them up to MTB's, Many of the riders put in significant time grooming the MTB trails and single-track DH runs.
