Might be a bit hard to work out in places and I understand there could be some abuse of this system but instead of trusted people having to put 20-30 vouches in their Signature, there could be a thing under Forum posts that says Verified Vouches: and have the amount on there. Each Verified Vouch that goes on there will be verified by someone so their not vouches for training someone from level 1 to 5 or some bullshit like that, and only Vouches that prove they are trustworthy[EX: Training strength from 60 to 99 while 10 mil is on the account] will count as a Vouch.
It will go as follows.
Forum Posts: 649
Verified Vouches: 4
Something like that.
I know it probably won't work out but just thought I'd throw my idea out there.
