I must have done something incorrectly yesterday because now I can't edit my original post so here's my updated list (for now).
There is a forum-wide setting that restricts editing posts after a few days, so you've probably run into the time limit.
Also, and my apologies if I'm telling you something you're already bearing in mind, but we expect a number of things to change in just a few days (!) when the full game releases, and obviously there's not going to be any changes made by Larian in response to feedback between now and then. If you're planning this thread to capture detailed feedback that you want Larian to pick up on, then you might be better off waiting and reviewing the release version. We're of course perfectly okay to chat about what we're hoping to see come the 3 August, but I suspect that Larian won't be combing Early Access feedback any further, and instead will be waiting to see what we make of the full game.
