A few dozen non-Princeton users are using the Guest Account Provisioning Service to access the blog admin interface. The longest duration for these accounts is one year after the request date; however, it is possible to request a reactivation of a guest account for an additional year.
If you find that you can no longer log into the blog admin interface with your guest account, first check on the status of your account in the Guest Services section of the Guest Account Provisioning Service site. You should try to use the "Request Password Reset Code" for your account. That will generate an email with a link. Opening that link will tell you whether your account has expired.
If your guest account has expired, and you still want to access your blog; send an email to firstname.lastname@example.org, and we will request a reactivation.
