for beginners if comments should be:
1. If you have a brief discussion you can do 2 ways with replays or with a quote
2. If the discussion is very long almost half tread or one tread, don't comment with the quote, because later it will look like spam. Better with replay.
I think so. Even some comments that only quote. No comment. I think it's useless. Very many do it only to raise ranks below the Junior Members.
