Better Notifications for People Posting in Your Threads?

Many times, people will post in my threads from a few weeks or months ago, and I won’t be notified in any way. I’m not sure how the yellow/gray light system works, but it seems not to not stay lit up for unread posts after a short time. Is there any way a CC admin could fix this? For those who have thousands of posts, it is unreasonable to peruse their entire list of previous posts to chance upon unread comments.

Maybe a notifications tab, similar to that on Facebook?

Go to “Thread Tools” on the top right of the first post, just above where it says #1. Use the drop-down menu to choose “Subscribe to this thread” and you will get notifications each time someone posts in that thread.
