So, I was called by a friend while at work today and he told me his account was denied due to naming rules or some rubbish.
He was Vito von Ismay and his e-mail address was email@example.com (I believe. It was yahoo or hotmail).
From what Syn's said before, his account would have been deleted due to Varick not having been level 2 and therefore that shouldn't be a cause of concern. The Ismay name isn't canon to my knowledge. He's a veteran and more than entitled to the Ismay name, not to mention having our consent.
Yes, ideally with an e-mail to firstname.lastname@example.org and/or email@example.com with approval from a current Von Ismay for him to use that name, as the people doing join requests can't automatically know that he has such permission.
