Scams

So I have received two emails lately that I know are scams. Both are asking me to set up an account here so they can transfer money to it from a bank in Africa. Then I would be able to keep 50% of the money while I send them the rest of it. I have read about these scams in the paper so I know they are bogus and that I would end up with a bounced check and a huge debt. The problem is I want to send them to someone who can look into these scams and I need websites or emails addresses. I know they are available because I accidentally found one one time. Unfortunately my brain doesn't process or remember email addresses easily. If anyone knows who I should contact please let me know. I would really appreciate it.
