Actually, We could make the community decide - on the Star rating, you could have a check box for "Recomend for Best Of Vault" or something phrased better.
Then the mods just move the maps that have a high enough "score"
And while we are at it, a CS and HL? mod vaults would help also - there's no rush in putting everything we have now in the right place, just encourage the news maps to be sorted properly.
