Many libertarians and voluntarists are involved in alternative news websites. Most of those websites allow for commentary, and many of them allow for story submissions. If you regularly browse those sites then consider making it a point to make a story mentioning the Free State Project (or at least NH in general), comments mentioning the Free State Project/NH, and possibly even a link to the Free State Project such as in your signature line if the site is a bulletin board style website.
Here is a recent example of a story that mentions the Free State Project at the very end of the story:http://www.abovetopsecret.com/forum/thread763746/pg1
Most of the people on alternative news media sites have never even heard of the Free State Project! Yet, many or most alternative news websites have a readership that would be interested in learning or participating. The example story got to the front page of the website. I've also seen stories exclusively related to the Free State Project get quite a lot of attention.
Here is the best list I've found of alternative media sites that would be perfect for FSP members to start reading and commenting at:http://www.newsblok.com/
