Oprah just had a repeat of a show she did about scams on yesterday.  I would check out her website and see what they have posted as ways to check this stuff out.

 

I know a couple people on there that got scammed went on to Yahoo groups and put in info from the "company" they were working for and got a list of scams going on with them.  There was an expert on there and he was talking about a way to check on banks and such that checks are written out of, but I can't remember...it might be on the website
