I've noticed it is really common here, people post replies to threads without reading the thread to see if the answer has already been given. It is like they read the first post, don't give a care that there are dozens of posts replying to it, and they reply as if the other posts don't exist. It is really annoying and insulting to those that have already put an effort into reading the thread and posting something thoughtful and helpful to the conversation.
It is really annoying for you, huh? Then why you think you can stop that happen by making a thread like this?
Give DP a favor if you see one please just click this icon at the upper right of the Thread/Post box and report it to mod. That's what I always do.
