Q: I am trying to login and it saying my token is expired? What does that mean?
A: Tokens are created to help you retrieve your password or confirm/create your account. Sometimes they expire after some time. If you are trying to retrieve your password, go back through the password retrieval process to have another email sent to you with a new token.
If you are trying to create/confirm your account, have the manager, who sent the original registration email to you, re-send a new one.
