New members are requested to familiarize themselves thoroughly with the forum rules (links are provided below) before posting, to abide by those rules, and to actively participate in technical discussions. The primary task of the moderator is to maintain an orderly environment for technical discussions on the forum. Please handle unread posts promptly, and take action against those who violate the forum rules. Special note for moderators: When managing posts, start from the management divider and go through all posts sequentially from top to bottom; after that, move the management divider upward. Once it has been moved, check again to see if there are any unread posts below the divider ； Be careful not to miss anything during management; try to complete it in one go, and definitely do not raise the management divider before finishing the management process. Please ask the moderators to pay more attention to rating the posts from other users; it would be great if they could also provide comments and replies. This way, those users can participate in discussions and improve their skills, while it also encourages more users to post and engage in conversations ； All moderators need to increase the number of posts they read; they should not stop checking posts just because other moderators are already handling them. If there are posts that have not been rated or have received insufficient ratings by other moderators, those ratings can be added ； Please promote high-quality posts and help requests posted within 3 days with no replies. For particularly valuable posts, give them recommendations, push them to the top, and mark them as highlights (for these three actions, first obtain support from other moderators in the management group) ； Advertising posts, meaningless posts, and spam posts must be deleted promptly. At the same time, review this person’s other posts: delete those that can be removed, and report those that should be reported. All illegal posts posted in the Machinery section need not be moved or edited – they should simply be deleted with a record of the violation made ； Warnings for posting violations, alerts, etc. – in theory, those who continue to violate the rules despite receiving such reminders will be placed on a mute status, with the duration of this mute period increasing gradually depending on the circumstances; in severe cases, the person who posted the content will be banned from accessing the platform.
