International High IQ Society – Recommended, especially for online interaction. Entirely online, except that they have one or more gatherings each year. If you join, you are automatically a life member, which is nice. The message boards and chat rooms are good places to communicate with other members on a variety of topics. There are regular tournaments and other competitions that you can take part in. An excellent and inexpensive place to enter the high IQ world, and a decent stopping point if it fully meets your needs. Note that over half of the membership is from outside of the US (mostly Europe), so expect the political and cultural tone to reflect this.
