Since nothing much more has been said on how the system works Ill explain a little bit more. The system basically works on points and rep power, by default forum admins have a fuxed reputation poer where as regular users and moderators power is dependant on a few factors. The reputation power is how many points you can add to someone elses reputation. The power is dependant on a few factors including post count, reputation points (not power) and how long you have been a member. So to sum that up your reputation power ISNT the same as your reputation points and is generally lower. The more posts you have, the more points you have and the longer you have been registered, the higher your power is and therefore the more points you can give to other members. The green blocks ( and ) as far as I know represent 100 reputation points each possibly more once you get over 500 points and they then become a brighter green for the second group of green blocks and the brighter green blocks are per 200 points after the first 500 points. You wont see many of those til the system has been in use for some time though. Grey blocks like mean you have exactly 0 reputation points and dark blue blocks like mean the user has disabled showing their reputation. I wont go into details about the negative side of reputation as that is disabled for regular users. If anyone else has any questions feel free to ask.
