You'd best email firstname.lastname@example.org . Wait for an answer from an actual person before writing again.
It might be Tuesday before you hear from an actual person, as there's an accumulation of help requests over the weekend.
You will get an "auto-reply" email. Keep it, as it has your ticket number. If you don't see it, check your email's "spam/junk" folder. Don't answer it. If you do, your original ticket will be kicked to the end of the "Help" queue.
