I think they've received over 100,000 tips in the last two weeks so I'm sure they are sooo busy right now.
Send them the information and they'll act on it. If you want to talk to someone, just wait for them to get back with you I guess. I'd definitely leave the information on the website, though. That way they get a concrete tip in black and white and your message gets to them. . .
My little contribution to the war effort is being documented!
