QB45 is run by a volunteering bunch of jolly individuals. If you have any questions, problems, suggestions, comments, or complaints with QB45, then feel free to e-mail them to firstname.lastname@example.org. Someone will get back to you as soon as possible, and we'll do our best to help you out.
However, there are other ways to contact the staff at QB45. Posting on the forum is one of them. Another way, that allows you to contact any specific staff member, is to just send them a private message (this requires that you have an account on QB45 and are logged in).
