We haven't set any specific guidelines for how one becomes a Moderator. The users that have Moderator status are long-time MoG supporters that provide valuable information regularly. I can say that if you are constantly responding to other peoples questions with accurate info and posting new info, we will contact you and grant you Moderator status. JR1 was a recent power user that we granted Moderator status.
Seeing that you have been very active and extremely helpful over the past week. I would like to offer you Moderator status if you are still interested. Let me know
Moderators can edit discussions, add new ones and post them to the correct category and a few other things. We also have a Moderator only Discussion Group where you can discuss things that won't be seen by the public.
