Need help with PEX and block breaking permissions.

I just setup my permissions, but I want to setup permissions for block breaking and building. I want it so that default players can only break blocks that they build and can't break anyone else's blocks. Can someone help me out to setup this permission.
I also have all of the essentials plugins and modifyworld.jar installed if that helps.

Code:

groups:
    default:
        default: true
        options:
            rank: '1000'
        permissions:
        - modifyworld.chat
    Member:
        prefix: '&0(&8M&7ember&0)&7 '
        permissions:
        - modifyworld.*
        options:
            rank: '900'
    VIP:
        prefix: '&0(&eVIP&0)&7 '
        permissions:
        - -modifyworld.mobtarget.monster.creeper
        - modifyworld.*
        - essentials.home.others
        - essentials.sethome
        - essentials.sethome.bed
        - essentials.delhome
        - essentials.kit
        options:
            rank: '800'
    Moderator:
        prefix: '&0(&1Moderator&0)&7 '
        permissions:
        - -modifyworld.mobtarget.*
        - modifyworld.*
        - essentials.ban
        - essentials.home.others
        - essentials.sethome
        - essentials.sethome.bed
        - essentials.delhome
        - essentials.kit
        - essentials.fly
        - essentials.togglejail
        - essentials.unban
        options:
            rank: '100'
    Admins:
        prefix: '&0(&4Deputy Owner&0)&7 '
        permissions:
        - modifyworld.*
        - permissions.*
        options:
            rank: '10'
    Owners:
        prefix: '&0(&4Owner&0)&7 '
        permissions:
        - modifyworld.*
        - permissions.*
        options:
            rank: '1'

    SgtDeathHound:

Get either WorldGuard or PreciousStones.

Since you're the owner give your self the perm - '*'
it will give you all permissions.
If you're using worldguard you will need to select a region to protect and make someone
the owner, the others except you cannot break it.
For PreciousStones you need to place a block such as a diamond block
for city protection and only the placer can break.

Either one is good, WorldGuard is recommended for very big and precise regions and preciousstones for small houses or buildings.

Also i made a default permissions.yml so you can see the spacing.

Fix your permissions file to the correct spacing as the link above.
If you need to test your server and see how it will look for default users, use a fake account such as newuser123 and test it out.

 

Ew, no, don't give yourself *. It's horrible practice and me sees so much stuff up. It gives you nodes by default nobody should have such as silence.canttalk meaning you can't talk.

Give yourself OP, way better. Also, PEX is horrible: http://goo.gl/MHhbl

 

I agree don't use '*'
