How can I make a gift from my IRA, appreciated stocks, or through my will or living trust?

It's easy to include us in your will or to make us a beneficiary of a life insurance or retirement plan — just include or name and tax identification number 68-0384748 so that we can be accurately contacted.

How can I connect with other Members in my area?
We have a few regional groups and increasing interest from members around the world to have one in their area. You can join one of our Meetup Groups, or start one in your area — and we have prepared a Meetup Guide to help you get started!
You can also start a Facebook group and we encourage any member looking to start a group to be inclusive of anyone that is interested in learning more about long-term thinking (your participants don't all need to be members of Long Now).
What do you do with the income from the Membership program?
Members provide essential support to the Foundation; over 30% of our operating budget comes directly from member dues. The income we receive from membership goes directly to operational costs for projects and programs like the Long Now Talks, our monthly Member newsletter, social media team, digital infrastructure and running our office in San Francisco. Thank you for supporting us!
How is the Member card designed?
Your Long Now Member card is made of stainless steel and individually engraved with your membership number. The design on your Member card is the outline of the rete, the curving arcs on the face of the 10,000 Year Clock that Long Now is building. The two widest arcs of the rete delineate the range of view of the night sky as seen from the earth from a sea level elevation. The two narrower arcs delineate the range of view of the night sky from a high elevation. The two arcs that meet and point show the location of the celestial pole, which is currently the North Star, Polaris.
How can I get a replacement Member card?
If you've lost your Member card, send an email to membership@longnow.org. and let us know. We ask for a $25 payment, which you can make online, to cover the cost of re-engraving your member number and shipping your replacement card.
