Inactivity in the f-modding department. Although Forum Moderators do not have set expectations as it were, it only makes sense to keep the team fresh and active by allowing the less industrious to step aside in favor of others who would do more.
That, in a nutshell, is what came to pass for me, and I must say I entirely support it. As grateful as I was to serve as a Forum Moderator for a time, I must say it's quite refreshing to be back in grey and not feel I should be doing something more responsible with my online time.
