Is Seeking Arrangement any good?

SeekingArrangement is a niche dating site that targets specific users. Since it is not a general dating site, some people who stumble upon it accidentally might be put off by its concept. However, it does a great job of offering a safe environment for the kind of relationship and connection that it encourages.
