Between the New posts and search icons, why don’t you put in the item “Last 300 posts”. That way, a person can read the last 300 posts on CC, no matter the category.
Well, since I got a response last time, I thought I would try again. 
I would love to click on the parents forum and read the last 200 or 300 posts, regardless of thread. How hard is it to make this happen?
