Green text would be ugly af.
How about instead the thread title text is gold and the page number is gold if you've replied. It's easier on the eyes.
Still I support the concept I can never remember what page I responded on on super long threads.
While that is true.
You'd have to track every thread you reply to to see more than 25 threads you've participated in.
Not to mention it doesn't tell you where your post is, which would be useful when tailing it on a long thread.
