Anytime you want to see replies, you can see the total of replies to any post just by opening up the section, say Politics & General Discussion and every topic is there with its replies and views listed next to them. When a topic has replies, you just open the topic and it's all laid out before you, in the order in which it was posted.
Quoting is going to become important so that responding to things way down the page will show the quote and then the response.
There's a small learning curve as the forum doesn't have what's called "threaded posts" like the old boards. It has sequential posts.
When you come on board, click on the SHOW NEW POSTS at the top right (under administration). See my posts in the questions, comments, etc board for more details.
