I see that there are quite a few issues reported to the issue tracker, and then closed because they should first have been discussed in the forum so that the developers can verify that there is actually a bug.
I’ve also noticed that one of the very first things stated at the top of the forum page is that one should “file bugs directly in the issue tracker” – to me this sounds like “don’t start discussing bugs here, please go directly to the tracker”. Of course this might only refer to definite bugs, but I don’t think this distinction would be clear to all users. Maybe clarifying this could help?
Also, the SyncThing documentation at https://docs.syncthing.net/ discusses the issue tracker before it mentions the forum. Maybe switching the order could also help a bit? And explicitly stating the rules there as well (the distinction between reporting definite bugs in the tracker and “what you think is a bug” in the forum)?
In any case, thanks for a great piece of software!
