First of all, thank you!
I found that information very useful.
I'm exploring the field, generally, and you are right- using this kind of services- does seem to be "not right".
But the thing is, I wanted to understand how it works. So if you have some information on that, of the technical side, I'd really appreciate information on the subject. Or maybe someone can point me to some source of information?
Again, I really appreciate your reply. It gave me some new points for my research
Thanks!
