PackardGoose.com doesn't have a website privacy policy. With some browser settings, this means cookies from the Goose won't be saved. In your browser, you should be able to change those settings.

For Internet Explorer 9, click on the gear and go to Safety > Website Privacy Policy. You'll see a nice overview of all the websites you are currently visiting: in this case just the Goose, but on other websites, tracking sites and ad sites may also be listed.
Click on the website of your choice to select it: in this case, both www.packardgoose.com and the packardgoose.ploeg.ws/messageboard.
When you select it, click on Summary. Tick the Always Allow dot in the list, then click OK, and you should be ready to go!

How does this work on other browsers? Let me know!
