The best way to contact the staff is via the forums as they are checked daily. Simply register with a valid e-mail and then post your question in the Major General forum.
If you'd rather not post your question in public, consider sending a Private Message (PM) to a staff member listed in the FAQ (you can choose the recipient for your PM from the drop-down list).
Finally, if you have a question but are hesitant to register on our forums, you can send an email to firstname.lastname@example.org. Be sure to put 'THAIN' in the subject line to avoid being overlooked as spam.
