Now that we have *quoting... and assuming that some Members will very familiar with it from elsewhere, and some won't...
There's lots of netiquette advice out there, so here are my top suggestions:
Do trim the quoted section to the minimum that is needed. (I like to add a marker to show that I've done this... )
Don't read someone else's quote of your post as disagreement. This can happen by mistake very easily. Simply as continuation of the quoted topic.
