Core

The term Core refers to members that are integral to the group, whether that be through sheer volume of posts or just being well known in the group. Posts from core members are more likely to appear on the news feeds of lurkers because of the facebook algorithm - probably.

Additionally, the term Old Core may be used to describe members that were once atop the figurative MDCJ Mt. Olympus, but have since fallen from glory. They are still remembered by many members to this day, but either rarely post or have entirely left the group. They will be missed (mostly).
