The forum format should be changed. Newer comments would be posted at the top, so people don't need to wade through all of the previous comments to find the new ones.
You can check your My Discussions page to see the # of comments since your last post, and clicking the link leads you directly to your post so you can read downward from there. Also, having the new comments first would be weird if it's a discussion; you'd have to find the last message you read was, then read upward, then possible go to the previous page, scroll all the way down to the bottom, and continue.
