Infraction Appeals has been changed to post threads through a form as well; here too it can be accessed through an "Appeal your infraction" button that's found where you normally see "Post new thread". Here too the idea is to streamline the process by formatting appeals better and filtering out threads that should be posted elsewhere (e.g. PS appeals) more easily.We've added a Discord ban appeal forum, which can be used for bans from both the main Smogon server and any server listed in the Discord side server directory. We haven't had a streamlined way to handle these so far, so hopefully this will come in handy.
Rather than using conventional threads, in order to make sure all threads are formatted cleanly, the forum uses a form (which can be accessed through where normally the "Post new thread" button is found), which then posts a user's replies as a thread into the forum. Similarly to infraction appeals and PS! discipline appeals, threads can only be viewed by Discord staff + community leaders and above and by the user posting them.
This setup may still be subject to change because right now ban appeals are kind of shoehorned into it, but that's no reason to hold off on making this change altogether.
