I’ve been blogging at http://www.teachingexperiment.com, a domain which I registered through WordPress. Unfortunately, the credit card which I used to register the domain name expired, so it didn’t auto-renew the domain. I would like to register a different credit card to renew the domain, but WordPress won’t let me login using either of the usernames that I have (teachingexperiment or Carla Meyrink). How can I log back into my WordPress site? If the domain name is no longer available, have I lost my content?
