I have been seeing a lot of double posting, where you make one post and then your post is the next one. I have gone through and deleted several posts just this afternoon that were doubles and I don't want to see it anymore. If you need to add something to what you have already said, use the "edit" button and add it to that original post.
The only time that their is an exception is when the "double post" is seperated by a time span of at least 12 hours. As of now, I am just editing the posts with a reminder and deleting the doubles but I will have to take more action if I continue to see users doing this.
