Please be judicious with your use of the quote button. Feel free to edit the quote to highlight just the selection, ask yourself if it's necessary to quote the guy who posted just before you did, and instead of quoting a whole screen worth of text, just precede your post with "@Other person". Some people can find it annoying to scroll through whole huge blocks of quoted text that aren't necessary to clarify to what you are referring.
I'll demonstrate the "@" thing if you don't know it.
