There doesn't seem to be a way any longer to see a lists of people who have signed up but not been approved? The Accounts page no longer lists any account requests, even though I know they exist because I have emails from the system. If I go to the person's page directly, I can send them a token. But the email appears to be my only way to know who those people are.
Also, where do I configure the email that gets sent? I like to include some basic instructions on how to edit cards when I approve people's accounts.
The cards formerly known as "Account Requests" are now known as "Sign up" cards. It looks like we did not update the *account card with this name. I'll try to get that migration in the next release. In the meantime you can look at those cards directly (eg http://teenwolfwiki.com/sign_up+*type+by_update)
System emails are not configurable, but that's actually fixed in 1.13.1, which is due out very soon.
