Well this might sound a bit "odd" but as with a new year which you change a something in your life.
I say why not do the same with the Pre. It does not have to be something major. Giving up something, or taking on something new just for the Pre, you can even make more then 1 pledge if you want. Can be something silly like pledging not to use Pre puns.
If you want to join me and make your own Pre Pledge, do so. It does not have to be forever if you do not wish it to be, just till the Pre is launched.
