The fastest way is to connect to the IRC and join #help. A few of our admins idle there. If you cant find what you're looking for in #help, then you can try #anonops.
Ask around in there and someone will probably be able to point you in the right direction. If all previous steps fail, then you could type !staff and PM one of the staff members online. (Remember that staff hate being PM'ed so I would avoid this at all costs). You could also ask one of the channel operators. If no one is available, leave a message.
We also now have email, if you want to contact a particular staff member by email, use (nick)@anonops.com. General things can go to firstname.lastname@example.org.
