@tomw and @pseudoxiah: Being a domain reseller, I can tell you exactly what this means and what Frank did.
Approximately one month ago the oswd.org domain expired. I contacted Frank, then he renewed it for one year (until September 2010).
Now just a few days ago on November 9, 2009 he added one more year of renewal to the domain name, so now it will expire in September 2011.
Frank also turned on domain transfer lock, so that way no one can transfer the domain away unless he unlocks it from within his domain registration control panel.
I know a lot of people really want the oswd.org domain name, but at this point the only way you or anyone else would get it is if Frank sells it or if in September 2011 it expires and Frank doesn't renew it for 60-90 days, then it will go on the open market.
Basically because you have a domain expire/snap watch in GoDaddy for the domain name, anytime Frank makes changes (renewals, domain lock/unlock) you will get a similar notification.
