The newest addition to the rep system is ability to view the the latest rep that you have given (up to 5) as well as the reputation power number. This number is based on different values including length of account creation, forum rep, amount of rep given to others... and other aspects which shall remain shrouded in mystery as per the devs' intentions. This number is tied to the thumbs up function and will add the value listed to any player's rep; for instance the 37 that is my current rep power will add +37 points to any user I award with a thumbs up, which is substantially more than the +2 associated with the thanks function, it also allows you to keep your anonymity unlike the thanks feature
