My suggestion is make it so the authors get like 0.5 points and F$0.5 when people reply their post.
Because authors would more interesting topics (that's the purpose of a forum)
This is just a little suggestion. You can agree or disagree. Please don't yell at me.
I DISAGREE!! !C#!#$@#$!#
Seriously, I disagree.
It will provoke more spam that interesting topics.
Some posts are just "full of replies". This would lead to abuse in return.
