Lastly, I have some experience in this, and I would suggest that you must do a thorough check of all information provided to you by the person themself or even sometimes by the family, as when you live in different cities/countries or even towns in the same city, you sometimes can't find out a whole lot about someone and their family and you don't want any bad surprises. Internet also has some horror stories to tell, but there are also some good stories. But isnt it the same in life? Internet is now part of our lives too :)
I would second that.
