Administration serve as leaders of a forum. Their purpose is to make sure that the goals that they set are worked towards and reached. If their goals are relational focused, they should interact a lot with the members. Some leaders can be friendly, without being friends. If there is an uncomfortable message to be delivered, it may be optimal to send in a moderator, or other representative. A successful administrator puts successful and potentially successful team members, within the organization. This leader is focused on making other's succeed so that the goals and dreams of the organization can be fulfilled.
I recommend not looking at your personal stats, but on the growth of the forum. If your goals are being reached or surpassed, then you are doing awesome. If your goals are not being reached, with your creativity, you will discover what to do, or who/what could be added or redefined. By bringing up these questions, you are the administrator that you strive to be.
