DIscussion Forum Layout

So, in setting up my site, I'm currently setting up with the EasySocial. I've dealt with discussion forums in the past, but never looked into this. Rather than having a standard forum set up. Is there a way where a topic has it's own thread show. Similar to that of this site where there the discussion can be viewed by line.

Check out this site for further details: Here

To reply back, it would look like this.

Here is another site with what I'm trying to accomplish: HERE

Thanks
