You're proceeding to access the listings of serious applications for personal exchanges, which are exchanges that happen between just two, or at most a few people. These programs differ with the common ESN exchanges as in if you choose someone you will not get along great with, you and the other person will not have the chance to spend their time with other people like you would in group exchanges, and you'll have to spend all your time with only that person. That fact aside, one on one exchanges with the right person will establish a lifelong and closer friendship than any other group exchange would. We hope you find the person you imagine!
