I'll just be direct here, so as not to be overly long.
The 2.9.1 forum thread is past 1600 posts, and I have no doubt it will hit 2000 posts shortly.
The problem with that thread is that it's crushing under it's own weight. The same or closely related problem gets solved over and over. People can't find their problem because the answer is either in a threaded response which gets lost to time or the search in NING can't find it for what ever reason.
So here is a solution that I think will go a massive way toward reducing redundant answers and people/helpers can focus more in specific areas.
So instead of making a single 2.9.2 release thread, how about making a thread for specific areas of Arducopter 2.9.2.
Arducopter 2.9.2 Software Install and Hardware functions (New 2.9.2 users Start Here)
Arducopter 2.9.2 Acro/Stable/Tuning Thread (Step Two)
Arducopter 2.9.2 Alt Hold/Loiter/Position Hold Thread (Step Three)
Arducopter 2.9.2 Missions/Way-point Navigation/Auto-Flight Functions (The last thing you should be testing)
Let's say release 2.9.2 gets another forum 2000 posts. Splitting this 4 ways (as above) drops that number to only 500 posts (in theory) in any given area. Plus it segments it out in the same order that most people have to (should) deal with when installing a new version of Arducopter.
But it's gets way better.... Because with it organized like this, there will be far fewer repeat postings, since now it's possible for people to actually read the entire thread that deals with the issue they are working on the time. This should cut back the posting where people give up on reading the entire thread and post a new question at the end, one that has been answered already.
By doing this it takes the pressure off the Wiki somewhat. Because the Wiki is constantly chasing a moving target. Solutions are found and results posted in the forum, long before they can, or should be, chiseled in stone on the Wiki.
Anyways, sorry this is so long, I was thinking about it in the grocery store today, and I think it's a really good idea.
