50% activity makes you member; 50% activity is intended to indicate a noticable contribution to the forum.

90 days as member makes you a senior member; senior means older, no?

The previous system was that you became senior member at member and 6 months from your join date, but then long time lurkers would pop out of the woodwork and become instant senior members.
