If you're replying to the post above or even one or two above then there's no need to "quote". Or even if the thread is a few pages & it's still on the same subject, again, no need to "quote".
If the post I want to reply to has 'got lost' in a thread or I'm answering to more than one person then I like to put @ & their name.
As in ........ @Rusty Nuts, I'm pretty sure you're correct.
