I like the 'one notify per post' limit. The old way, I'd check my e-mail some mornings and have 20-30 messages concerning single errant post made while I was sleeping. (It's a busy forum.)
My beef is the name "notify". Some users take it to mean that the button is used to notify THEM that there has been a reply in that thread---like a "watch this thread" button. I was much happier when it was called "Report Post" with a whistle icon which was so obvious that even a complete idiot could understand what it meant.
