There is an option for the forums called "nested" threading. What this means is that you can reply directly to individual posts by clicking reply. OR you can still go to "new post" at the bottom.
Now it is easy to create a "quote" like effect by creating blocked text. All you need to do for that is: >
which looks like this
So you can use that to highlight particular phrases you are responding to.
But I thought I would ask you guys if you wanted to try the nested option as well.
Also to make a clickable link you just need to put brackets  around the link.
