Using the dropdown select options you can filter which reputation comments to view in the reputation archive:
All | Positive | Balanced | Negative
Choose to list all, only positive, only negative or balanced reputation comments. Balanced comments are those which have had no effect on the reputation points total - often received from newly registered members.
Reputation Received | Reputation Given
Choose to list reputation comments you have received from others or those that you yourself have given.
You may also have a username text input options:
From Username | To Username - Enter a username here to filter the list to show only reputation comments received from or left for that particular member.
