Wayne,About using an e-mail that doesn't show your IP.Is there anything wrong with using a free service like Yahoo or MSN? As much as I know about it that would only go as far as the ISP's IP,Correct? Maybe an experienced hacker could go further but I don't see a scammer wasting the time for one.I stop contact after the money letter or translation agency letter if I go that far.Any forseeable danger/problems with that?
One thing I didn't see you mention was regarding photo's.They almost always have a letter or 2 wanting your pic.,I NEVER send mine and if I do I have some that are as fake as they are.

Another thing is them wanting to call you on the phone.THAT is not a good idea giving your land-line number too much info can be retreived with it.I tell them I only have a cell and don't have overseas capability,that has ended that right there.
