What the heck is "comment rep?" I thought it was a record of how many comments you left on stories, is that the case? 

If AFF is going to make changes, I wish they'd send messages to each user as they do so. Be it through a PM, a wall post, or something. Did that happen, and I just missed it? But I saw a lot of people asking what happened. UGH! Does anyone know that this is???
