More titles, relating to mcMMO.

Okay, recently the new titles were implemented, and I figured I'd help suggest an expansion.
We all know that these titles are here to show off our success and such.
I figured it would be a good idea for us to have titles showing off our mcMMO skills as well, because personally I don't want to sell diamonds or iron, because I want to use it to get my skills up.
So far I've came up with:
-Rookie (Skill) -level 100+
-Skilled (Skill) -level 250+
-Advanced (Skill) -500+
-Pro (Skill) -750+
-Elite (Skill) -1000+ (Please note, mining goes to 2000)
I hope you like the idea, also some skills may go through slight name changes to make sense.

this is a good idea
I also think the iron miner, gold miner, diamond miner etc. should not be bought... but base on mining rank
