“The homeschool directory” is list of homeschooling support groups in North America. It is organized by state and takes about 30 seconds to submit your site.
There is also a section to submit your homeschool related personal blog or homeschool related site. The directory is totally free- no reciprocal links or anything required. Just fill in name of your group, and relevant details i.e URL and brief description of the group and submit. There is a field for email but that is not shown and you will not be contacted, etc.
