Hi Adam
The coloured bars indicate your post count, as your post count increases so does the red bar.
The scales of justice allow you to give a person a positive or negative reputation/feedback for a particular post that they have made, so if someone makes a very informative or helpful post then they deserve to get given a positive reputation. As your reputation increases, so does the little green blocks under your post count.
The red and yellow cards are used for members to report to administrators if they see an infraction of some kind, i.e. a serious violation of the rules or slandering another member etc. Admin will review the infraction and decide on whether or not the infraction is justified. Once a member receives a certain amount of infractions, the system will automatically ban that user for a period of 5 days.
The red warning triangle is for members to report 'bad' posts to moderators, i.e. for minor things like spam or someone starting to get out of hand and needs a little slap to bring them back into line
Moderators will review these posts and take the necessary action, if necessary inform admin to take further action by deleting the post and/or speaking to the member via PM.
This is all done off the forum, there is no fighting or arguing or bickering or questioning reasons etc on the forum, this is a reefkeeping forum and will be kept as such. All "politics" are promptly removed from the forum and are dealt with privately so that the forum contains nothing but reefkeeping information
We are very strict in this regard as I am sure you will appreciate that it leads to a very happy and informative place for the members to enjoy their hobby.
