Unfortunately there are a lot of users with a minimal amount of rep points. Rather then go through all of them (because it's starting to become very time consuming), we're just going to zero their rep if we see them posting. And about 90% of them will probably never post.
Anyway, that's just minor stuff.
I'm glad everyone likes the new system. Feel free to leave me lots of comments!!! w00t!!
It is very simple to turn the rep system into a comment system from this point on. Points would no longer be given, and everyone's reputation power would be zero. All past comments would remain in tact.
However, it is quite a bit harder to make this retroactive (and to delete the green bars and past points). It involves going into individuals' settings and manually changing their rep level to zero. This would delete former points, and preserve all comments.
