Shroud of the Avatar: Link Your Accounts!
The latest update from the Shroud of the Avatar Kickstarter project gives details on how to link your Kickstarter account (and, thus, your Shroud of the Avatar contribution) to your account at the official Shroud of the Avatar website (which, by the way, recently adjusted the layout of its forums).
And of course, once you’ve linked your accounts and your pledge is showing up properly in your account information at the Shroud of the Avatar website, you can adjust your pledge amount.
