For those who couldn't pay via Amazon or otherwise missed out on the initial Kickstarter drive, the PayPal extension is also now online. This extension is supposed to run through until February, and the rewards are the same as the previous drive, so there's plenty of time.
Finally, feature and avatar voting is now live for donors. The voting interface also appears to update with the current tallies, so check back often to see how things are going.
A heap more changes have been hinted at for donors over the coming weeks, including updated webpages and the first cut of a web client (wow), with work starting in earnest early next year.
For now, expect to see a lot more halos appearing in your friendly local digopile...
