Yeah. A lot of forums have topics that are permanently posted to top of the forum. Such topics are usually: "Beginners and Newbies"; "FAQs"; or "Tips on how to use this forum."
Anyone may post in these topics, but the first/original post of each topic is maintained, edited, and updated by a moderator and may include helpful links, etc.
"Rocket stove debugging facts" reminds me of "FAQs," or etc. The topic could have an ongoing conversation (like any other topic), but the original/first post (at the top of the topic) could be almost like a contents list, or main-page, which is edited, updated, and maintained as new "debugging facts" or "FAQs" are questioned, debated, and resolved within the body of the topic.
I feel like this would help the forum a lot. There wouldn't be so many posts that ask the same ol' questions. Also, a better 'search' interface would help. But I dont know how that works..
