Well then here it is again.
My suggestion? Well I think you should have mods that heavily mod one forum to keep an eye out for potiental, and once they deem a member qualified, trustworthy, and so on and so forth, then they should tell someone who can promote the member about him or her. And the mod or whoever, should give a valid reason, and if an admin or whoever deems the member qualified and thinks they need the person, then bam mod the member. As for promoting mods? Very good, but don't just promote a mod, follow what I said for promoting members to promote mods.
This is moving really fast isn't it?
