This is the Thread Prefix test

And honestly, it's on the poster to pay attention to where he/she is commenting. Everyone has a forum fail from time to time but in general, this just isn't a difficult thing and IMO is a perfectly reasonable expectation of members.

So I've been a member at mtbr.com for years, which is a mountain biking forum. It's enormous and has a ton of daily activity, and has a lot of sub-topics that all fall under the general heading of "mountian biking". The forum sections are broken down very simply, with a single section for each main topic. Basically the same idea as the historical, traditional, and contemporary sections we have here only on a much larger scale. Aside from an occasional mis-post, that forum functions just fine. Threads are started in the correct places and commenters seem to know exactly where and what they're commenting on. Someone who has questions about a new fork for his enduro bike or looking for feedback on a 1x10 drivetrain can expect to receive on target replies. That forum runs on the same software as xmarks, but with a well organized and IMO pretty simple user experience. If it works there it can easily work here.
