I've heard various ideas such as limiting it only after mods have expended their points (this will require implementing a cooldown to prevent a user from getting points again too soon). I want to hear your feedback, and I'll roll together something for the next major update of the site. Leave your comments
Unless we are hurting for comments I would assume keep the no modding in stories you've posted to. Barring that, I could go for not being able to mod anything after posting.
On another note, thank you for making all the story headline blocks be links to the stories. That was the one thing that was off to me and tickled the back of my mind every time I tried to click on the headlines and went nowhere.
