Hello, i'm developing a contact manager called "contacts", i got an idea which i would like to add to the program, i would like users to be able to share contacts through the internet, for example "A" person has one contact that "B" person would like to have it, the problem is i have no idea on how to do it, how to share data through pcs through the internet, so if someone can give me a hand with this one, i'll really appreciate it.

Thanks
