I'm not sure if these even exist, I went through some of the comments plugins but I figured I would ask here as well.
1) I would like the post page to automatically show any new comments without the visitor having to refresh the page. Say I was reading a post and someone left a new comment I would see the new comment right away without having to refresh the page.
2) If someone starts to leave a comment it locks out anyone else from adding a comment for a set amount of time. (I have my doubts about this one)
