I have been trying to add another wordpress blogger as an administrator to my site. They signed up a few days ago to wordpress. I followed all the steps and keep gettting the message that their email address was not found... although they do have a wordpress blog up and running. We checked the email address they signed up a number of times to ensure that it was spelled correctly. When they signed up, they also didn't receive a confirmation email either. Should they have? They then tried adding me as an administrator to their blog page and they got the same message that my email address wasn't found.
Is there some technical problem with the site? I see that tech support is temporarily down.
