The in-game messaging doesn't seem to be tightly connected to the forums, and we should change that. Almost all player discussion is done via Discord or #main these days, which means most opinions are not well thought out and are easy to ignore. People end up feeling disappointed.
My suggestion here is simple: At each maintenance, update the in-game greeting message to point out that a maintenance was done and forums have details. Asking for feedback via forums would also go a long way.
