GPF allows gradual introductions to potential penpals. Be general about your likes and specific about your interests in order to find a connection with someone who shares your specific interests, and whose general likes will keep you interested, and vice versa. Don't apologize. Be yourself. What could be easier!
Very well suited to find friends, maybe even a partner for life. I would recommend in any case!
I'm sticking with it and can only give the tip to everyone who is interested in exchange with other people / cultures to get involved.
I love sending letters to people all over the world. All in all a very positive experience with this site. I did experience one scammer but the site dealt with them very quickly.
