WoW Guild importer is back on. Please note it may take a few hours for your guild to be imported / updated, since there is a long initial queue. Things will return to normal in the next 24 hours.
The Importer says that my Guild doesn't exist on this server, though it doesn't ask for the server name. Above the Guild Import Section, under Characters, all the characters are outdated, level wise, and we're missing about 11 people.
