Registering here on the site is free and will get you access to more information on building Sustainable Systems as well as access to Educational Software as we get it up online. It also offers you the opportunity to become a SUN Member through your own contributions to helping the SUN Project grow.
There are no official Contribution standards in terms of Work or Money for Membership, since each person has different means at their disposal. We do encourage members with good means to assist on the financial level, since there are costs involved in running any organization, including non-profit ones.
As an organization, we do have a goal of creating a Demonstration Sustainable Community somewhere in the USA, and Investment level contribution is one way to become a part of that project. We will be providing more information about Investment Opportunities in SUN down the road a bit as we complete the initial phase of building the Information Network and Affiliate Membership. Look for more information coming on this in the near future.
Meanwhile, feel free to cruise around as we get up more of our content, and if you find it interesting Register here to get to know the rest of the people involved in SUN Community Development. We look forward to talking with you and building relationship, which is the most important aspect of any successful community.
