Junior is not a knock down, it's an upgrade. Someone correct me if I'm wrong but here goes:
1. Newbie= posts 1-49
2. Honorary Member= posts 50-99
3. Junior Member= posts 100-199
4. Senior Member= posts 200+
Then there's that whole moderator thing which would just consume my whole life if I were to attempt it.
Please add anything else that I don't know about.
