I hate to say it, 'cuz sometimes I find something in the old topics that still apply, but you may want to consider locking anything more than 3 years old…
Been seeing several posts in the forums that are just comments or questions on long ago resolved or closed discussions. You would think that starting a new thread would be best but that would just create more posts and lose original content - and lead to several posts with links to old threads…
Also, and I’m as bad as anyone else or maybe worse, seems like topics are more chat than subject related. Will do my best to refrain from just saying “that’s cool” and contribute to discussion but guess there’s nothing you can do about that
