We are sad to announce that Pownce is shutting down on December 15,
2008. As of today, Pownce will no longer be accepting new users or new
pro accounts.
To help with your transition, we have built an export tool so you can
save your content. You can find the export tool at Settings > Export.
Please export your content by December 15, 2008, as the site will not
be accessible after this date.

Our thanks go out to everyone who contributed to the Pownce community,
