Currently, when a feature request is made the only way for the topic to be locked is to contact a moderator and have them lock the post. I think adding a solution button to posts would be very beneficial as then it would notify users that the topic has been taken care of. It would be similar to roblox’s solution button, except when this solution button is hit the topic is auto locked.
but you could add a notice for example “thx for roblox help!”
Even though I could technically say that the topic isn’t accepting more replies, or that it’s locked it would make more sense for a button to auto lock the post for you without having to delete the post.
