I got tired of seeing a lot of people abusing the ranking system by making non-security related posts (world's longest thread, short story) and I was thinking, it would be nice if the person who starts the thread can specify whether the posts on that thread count towards elevating in the rankings. Something like a checkbox that says "Posts do not count" or something of the sort. That would mean that only the people who make relevant posts rise in the rankings. Could be something to think about. It could also have implications for abuse though, so let me know what you guys think.
Cheers,
