Process to becoming a Moderator.
1) Mods find someone they think would be a good mod.
2) They Go to the mod only forum.
3) Recommend this person to other Moderators and Admins.
4) The idea is discussed.
5) If there is a positive outcome the person in question becomes a Moderator.
The new Moderator will gain access to the Mod only forums.
The new Moderator also gain some (Not all) Silence/Ban powers.
A little M is placed next to the username.
However if a Moderator abuses the power of being a Moderator they will be reverted back to the average user by Admins.
I believe that is the process.
